-#
-# Brief guide to compile-time options of the code. More information
-# can be found in the code documentation.
-#
-# - PERIODIC:
-# Set this if you want to have periodic boundary conditions.
-#
-# - UNEQUALSOFTENINGS:
-# Set this if you use particles with different gravitational
-# softening lengths.
-#
-# - PEANOHILBERT:
-# This is a tuning option. When set, the code will bring the
-# particles after each domain decomposition into Peano-Hilbert
-# order. This improves cache utilization and performance.
-#
-# - WALLCLOCK:
-# If set, a wallclock timer is used by the code to measure internal
-# time consumption (see cpu-log file). Otherwise, a timer that
-# measures consumed processor ticks is used.
-#
-# - PMGRID:
-# This enables the TreePM method, i.e. the long-range force is
-# computed with a PM-algorithm, and the short range force with the
-# tree. The parameter has to be set to the size of the mesh that
-# should be used, (e.g. 64, 96, 128, etc). The mesh dimensions need
-# not necessarily be a power of two. Note: If the simulation is
-# not in a periodic box, then a FFT method for vacuum boundaries is
-# employed, using an actual mesh with dimension twice(!) that
-# specified by PMGRID.
-#
-# - PLACEHIGHRESREGION:
-# If this option is set (will only work together with PMGRID), then
-# the long range force is computed in two stages: One Fourier-grid
-# is used to cover the whole simulation volume, allowing the
-# computation of the longe-range force. A second Fourier mesh is
-# placed on the region occupied by "high-resolution" particles,
-# allowing the computation of an intermediate scale force. Finally,
-# the force on short scales is computed with the tree. This
-# procedure can be useful for "zoom-simulations", provided the
-# majority of particles (the high-res particles) are occupying only
-# a small fraction of the volume. To activate this option, the
-# parameter needs to be set to an integer bit mask that encodes the
-# particle types that make up the high-res particles.
-# For example, if types 0, 1, and 4 form the high-res
-# particles, set the parameter to PLACEHIGHRESREGION=19, because
-# 2^0 + 2^1 + 2^4 = 19. The spatial region covered by the high-res
-# grid is determined automatically from the initial conditions.
-# Note: If a periodic box is used, the high-res zone may not intersect
-# the box boundaries.
-#
-# - ENLARGEREGION:
-# The spatial region covered by the high-res zone has a fixed size
-# during the simulation, which initially is set to the smallest
-# region that encompasses all high-res particles. Normally, the
-# simulation will be interrupted if high-res particles leave this
-# region in the course of the run. However, by setting this
-# parameter to a value larger than one, the size of the high-res
-# region can be expanded, providing a buffer region. For example,
-# setting it to 1.4 will enlarge its side-length by 40% (it remains
-# centered on the high-res particles). Hence, with this setting, the
-# high-res region may expand or move by a limited amount.
-# Note: If SYNCHRONIZATION is activated, the code will be able to
-# continue even if high-res particles leave the initial high-res
-# grid. In this case, the code will update the size and position of
-# the grid that is placed onto the high-resolution region
-# automatically. To prevent that this potentially happens every
-# single PM step, one should nevertheless assign a value slightly
-# larger than 1 to ENLARGEREGION.
-#
-# - ASMTH:
-# This can be used to override the value assumed for the scale that
-# defines the long-range/short-range force-split in the TreePM
-# algorithm. The default value is 1.25, in mesh-cells.
-#
-# - RCUT:
-# This can be used to override the maximum radius in which the
-# short-range tree-force is evaluated (in case the TreePM algorithm
-# is used). The default value is 4.5, given in mesh-cells.
-#
-# - DOUBLEPRECISION:
-# This makes the code store and compute internal particle data in
-# double precision. Note that output files are nevertheless written
-# by converting the particle data to single precision.
-#
-# - DDOUBLEPRECISION_FFTW:
-# If this is set, the code will use the double-precision version of
-# FTTW, provided the latter has been explicitly installed with a
-# "d" prefix, and NOTYPEPREFIX_FFTW is not set. Otherwise the
-# single precision version ("s" prefix) is used.
-#
-# - SYNCHRONIZATION:
-# When this is set, particles are kept in a binary hierarchy of
-# timesteps and may only increase their timestep if the new
-# timestep will put them into synchronization with the higher time
-# level.
-#
-# - FLEXSTEPS:
-# This is an alternative to SYNCHRONIZATION. Particle timesteps are
-# here allowed to be integer multiples of the minimum timestep that
-# occurs among the particles, which in turn is rounded down to the
-# nearest power-of-two devision of the total simulated
-# timespan. This option distributes particles more evenly over
-# individual system timesteps, particularly once a simulation has
-# run for a while, and may then result in a reduction of work-load
-# imbalance losses.
-#
-# - PSEUDOSYMMETRIC:
-# When this option is set, the code will try to "anticipate"
-# timestep changes by extrapolating the change of the acceleration
-# into the future. This can in certain idealized cases improve the
-# long-term integration behaviour of periodic orbits, but should
-# make little or no difference in most real-world applications. May
-# only be used together with SYNCHRONIZATION.
-#
-# - NOSTOP_WHEN_BELOW_MINTIMESTEP:
-# If this is activated, the code will not terminate when the
-# timestep falls below the value of MinSizeTimestep specified in
-# the parameterfile. This is useful for runs where one wants to
-# enforce a constant timestep for all particles. This can be done
-# by activating this option, and by setting MinSizeTimestep and
-# MaxSizeTimestep to an equal value.
-#
-# - NOPMSTEPADJUSTMENT:
-# When this is set, the long-range timestep for the PM-force
-# computation (when the TreePM algorithm is used) is always
-# determined by MaxSizeTimeStep. Otherwise, it is determined by
-# the MaxRMSDisplacement parameter, or MaxSizeTimeStep, whichever
-# gives the smaller step.
-#
-# - HAVE_HDF5:
-# If this is set, the code will be compiled with support for input
-# and output in the HDF5 format. You need to have the HDF5
-# libraries and headers installed on your computer for this option
-# to work. The HDF5 format can then be selected as format "3" in
-# Gadget's parameterfile.
-#
-# - OUTPUTPOTENTIAL:
-# This will make the code compute gravitational potentials for
-# all particles each time a snapshot file is generated. The values
-# are then included in the snapshot file. Note that the computation
-# of the values of the gravitational potential costs additional CPU.
-#
-# - OUTPUTACCELERATION:
-# This will include the physical acceleration of each particle in
-# snapshot files.
-#
-# - OUTPUTCHANGEOFENTROPY:
-# This will include the rate of change of entropy of gas particles
-# in snapshot files.
-#
-# - OUTPUTTIMESTEP:
-# This will include the current timesteps of all particles in the
-# snapshot files.
-#
-# - NOGRAVITY
-# This switches off gravity. Useful only for pure SPH simulations
-# in non-expanding space.
-#
-# - NOTREERND:
-# If this is not set, the tree construction will succeed even when
-# there are a few particles at identical locations. This is done by
-# `rerouting' particles once the node-size has fallen below 1.0e-3
-# of the softening length. When this option is activated, this will
-# be surpressed and the tree construction will always fail if there
-# are particles at extremely close coordinates.
-#
-# - NOTYPEPREFIX_FFTW:
-# This is an option that signals that FFTW has been compiled
-# without the type-prefix option, i.e. no leading "d" or "s"
-# characters are used to access the library.
-#
-# - LONG_X/Y/Z:
-# These options can be used together with PERIODIC and NOGRAVITY only.
-# When set, the options define numerical factors that can be used to
-# distorts the periodic simulation cube into a parallelepiped of
-# arbitrary aspect ratio. This can be useful for idealized SPH tests.
-#
-# - TWODIMS:
-# This effectively switches of one dimension in SPH, i.e. the code
-# follows only 2d hydrodynamics in the xy-, yz-, or xz-plane. This
-# only works with NOGRAVITY, and if all coordinates of the third
-# axis are exactly equal. Can be useful for idealized SPH tests.
-#
-# - SPH_BND_PARTICLES:
-# If this is set, particles with a particle-ID equal to zero do not
-# receive any SPH acceleration. This can be useful for idealized
-# SPH tests, where these particles represent fixed "walls".
-#
-# - NOVISCOSITYLIMITER:
-# If this is set, the code will not try to put an upper limit on
-# the viscous force in case an implausibly high pair-wise viscous
-# force (which may lead to a particle 'reflection' in case of poor
-# timestepping) should arise. Note: For proper settings of the
-# timestep parameters, this situation should not arise.
-#
-# - COMPUTE_POTENTIAL_ENERGY:
-# When this option is set, the code will compute the gravitational
-# potential energy each time a global statistics is computed. This
-# can be useful for testing global energy conservation.
-#
-# - LONGIDS:
-# If this is set, the code assumes that particle-IDs are stored as
-# 64-bit long integers. This is only really needed if you want to
-# go beyond ~2 billion particles.
-#
-# - ISOTHERM_EQS:
-# This special option makes the gas behave like an isothermal gas
-# with equation of state P = cs^2 * rho. The sound-speed cs is set by
-# the thermal energy per unit mass in the intial conditions,
-# i.e. cs^2=u. If the value for u is zero, then the initial gas
-# temperature in the parameter file is used to define the sound speed
-# according to cs^2 = 3/2 kT/mp, where mp is the proton mass.
-#
-# - ADAPTIVE_GRAVSOFT_FORGAS:
-# When this option is set, the gravitational softening lengths used for
-# gas particles is tied to their SPH smoothing length. This can be useful
-# for dissipative collapse simulations. The option requires the setting
-# of UNEQUALSOFTENINGS.
-#
-# - SELECTIVE_NO_GRAVITY:
-# This can be used for special computations where one wants to
-# exclude certain particle types from receiving gravitational
-# forces. The particle types that are excluded in this fashion are
-# specified by a bit mask, in the same as for the PLACEHIGHRESREGION
-# option.
-#
-# - FORCETEST:
-# This can be set to check the force accuracy of the code. The
-# option needs to be set to a number between 0 and 1 (e.g. 0.01),
-# which is taken to specify a random fraction of particles for
-# which at each timestep forces by direct summation are
-# computed. The normal tree-forces and the correct direct
-# summation forces are collected in a file. Note that the
-# simulation itself is unaffected by this option, but it will of
-# course run much(!) slower, especially if
-# FORCETEST*NumPart*NumPart >> NumPart. Note: Particle IDs must
-# be set to numbers >=1 for this to work.
-#
-# - MAKEGLASS
-# This option can be used to generate a glass-like particle
-# configuration. The value assigned gives the particle load,
-# which is initially generated as a Poisson sample and then
-# evolved towards a glass with the sign of gravity reversed.

#-----------------------------------------------------------------------
#
# Brief guide to compile-time options of the code. More information
# can be found in the code documentation.
#
# - PERIODIC:
# Set this if you want to have periodic boundary conditions.
#
# - UNEQUALSOFTENINGS:
# Set this if you use particles with different gravitational
# softening lengths.
#
# - PEANOHILBERT:
# This is a tuning option. When set, the code will bring the
# particles after each domain decomposition into Peano-Hilbert
# order. This improves cache utilization and performance.
#
# - WALLCLOCK:
# If set, a wallclock timer is used by the code to measure internal
# time consumption (see cpu-log file). Otherwise, a timer that
# measures consumed processor ticks is used.
#
# - PMGRID:
# This enables the TreePM method, i.e. the long-range force is
# computed with a PM-algorithm, and the short range force with the
# tree. The parameter has to be set to the size of the mesh that
# should be used, (e.g. 64, 96, 128, etc). The mesh dimensions need
# not necessarily be a power of two. Note: If the simulation is
# not in a periodic box, then a FFT method for vacuum boundaries is
# employed, using an actual mesh with dimension twice(!) that
# specified by PMGRID.
#
# - PLACEHIGHRESREGION:
# If this option is set (will only work together with PMGRID), then
# the long range force is computed in two stages: One Fourier-grid
# is used to cover the whole simulation volume, allowing the
# computation of the longe-range force. A second Fourier mesh is
# placed on the region occupied by "high-resolution" particles,
# allowing the computation of an intermediate scale force. Finally,
# the force on short scales is computed with the tree. This
# procedure can be useful for "zoom-simulations", provided the
# majority of particles (the high-res particles) are occupying only
# a small fraction of the volume. To activate this option, the
# parameter needs to be set to an integer bit mask that encodes the
# particle types that make up the high-res particles.
# For example, if types 0, 1, and 4 form the high-res
# particles, set the parameter to PLACEHIGHRESREGION=19, because
# 2^0 + 2^1 + 2^4 = 19. The spatial region covered by the high-res
# grid is determined automatically from the initial conditions.
# Note: If a periodic box is used, the high-res zone may not intersect
# the box boundaries.
#
# - ENLARGEREGION:
# The spatial region covered by the high-res zone has a fixed size
# during the simulation, which initially is set to the smallest
# region that encompasses all high-res particles. Normally, the
# simulation will be interrupted if high-res particles leave this
# region in the course of the run. However, by setting this
# parameter to a value larger than one, the size of the high-res
# region can be expanded, providing a buffer region. For example,
# setting it to 1.4 will enlarge its side-length by 40% (it remains
# centered on the high-res particles). Hence, with this setting, the
# high-res region may expand or move by a limited amount.
# Note: If SYNCHRONIZATION is activated, the code will be able to
# continue even if high-res particles leave the initial high-res
# grid. In this case, the code will update the size and position of
# the grid that is placed onto the high-resolution region
# automatically. To prevent that this potentially happens every
# single PM step, one should nevertheless assign a value slightly
# larger than 1 to ENLARGEREGION.
#
# - ASMTH:
# This can be used to override the value assumed for the scale that
# defines the long-range/short-range force-split in the TreePM
# algorithm. The default value is 1.25, in mesh-cells.
#
# - RCUT:
# This can be used to override the maximum radius in which the
# short-range tree-force is evaluated (in case the TreePM algorithm
# is used). The default value is 4.5, given in mesh-cells.
#
# - DOUBLEPRECISION:
# This makes the code store and compute internal particle data in
# double precision. Note that output files are nevertheless written
# by converting the particle data to single precision.
#
# - DDOUBLEPRECISION_FFTW:
# If this is set, the code will use the double-precision version of
# FTTW, provided the latter has been explicitly installed with a
# "d" prefix, and NOTYPEPREFIX_FFTW is not set. Otherwise the
# single precision version ("s" prefix) is used.
#
# - SYNCHRONIZATION:
# When this is set, particles are kept in a binary hierarchy of
# timesteps and may only increase their timestep if the new
# timestep will put them into synchronization with the higher time
# level.
#
# - FLEXSTEPS:
# This is an alternative to SYNCHRONIZATION. Particle timesteps are
# here allowed to be integer multiples of the minimum timestep that
# occurs among the particles, which in turn is rounded down to the
# nearest power-of-two devision of the total simulated
# timespan. This option distributes particles more evenly over
# individual system timesteps, particularly once a simulation has
# run for a while, and may then result in a reduction of work-load
# imbalance losses.
#
# - PSEUDOSYMMETRIC:
# When this option is set, the code will try to "anticipate"
# timestep changes by extrapolating the change of the acceleration
# into the future. This can in certain idealized cases improve the
# long-term integration behaviour of periodic orbits, but should
# make little or no difference in most real-world applications. May
# only be used together with SYNCHRONIZATION.
#
# - NOSTOP_WHEN_BELOW_MINTIMESTEP:
# If this is activated, the code will not terminate when the
# timestep falls below the value of MinSizeTimestep specified in
# the parameterfile. This is useful for runs where one wants to
# enforce a constant timestep for all particles. This can be done
# by activating this option, and by setting MinSizeTimestep and
# MaxSizeTimestep to an equal value.
#
# - NOPMSTEPADJUSTMENT:
# When this is set, the long-range timestep for the PM-force
# computation (when the TreePM algorithm is used) is always
# determined by MaxSizeTimeStep. Otherwise, it is determined by
# the MaxRMSDisplacement parameter, or MaxSizeTimeStep, whichever
# gives the smaller step.
#
# - HAVE_HDF5:
# If this is set, the code will be compiled with support for input
# and output in the HDF5 format. You need to have the HDF5
# libraries and headers installed on your computer for this option
# to work. The HDF5 format can then be selected as format "3" in
# Gadget's parameterfile.
#
# - OUTPUTPOTENTIAL:
# This will make the code compute gravitational potentials for
# all particles each time a snapshot file is generated. The values
# are then included in the snapshot file. Note that the computation
# of the values of the gravitational potential costs additional CPU.
#
# - OUTPUTACCELERATION:
# This will include the physical acceleration of each particle in
# snapshot files.
#
# - OUTPUTCHANGEOFENTROPY:
# This will include the rate of change of entropy of gas particles
# in snapshot files.
#
# - OUTPUTTIMESTEP:
# This will include the current timesteps of all particles in the
# snapshot files.
#
# - NOGRAVITY
# This switches off gravity. Useful only for pure SPH simulations
# in non-expanding space.
#
# - NOTREERND:
# If this is not set, the tree construction will succeed even when
# there are a few particles at identical locations. This is done by
# `rerouting' particles once the node-size has fallen below 1.0e-3
# of the softening length. When this option is activated, this will
# be surpressed and the tree construction will always fail if there
# are particles at extremely close coordinates.
#
# - NOTYPEPREFIX_FFTW:
# This is an option that signals that FFTW has been compiled
# without the type-prefix option, i.e. no leading "d" or "s"
# characters are used to access the library.
#
# - LONG_X/Y/Z:
# These options can be used together with PERIODIC and NOGRAVITY only.
# When set, the options define numerical factors that can be used to
# distorts the periodic simulation cube into a parallelepiped of
# arbitrary aspect ratio. This can be useful for idealized SPH tests.
#
# - TWODIMS:
# This effectively switches of one dimension in SPH, i.e. the code
# follows only 2d hydrodynamics in the xy-, yz-, or xz-plane. This
# only works with NOGRAVITY, and if all coordinates of the third
# axis are exactly equal. Can be useful for idealized SPH tests.
#
# - SPH_BND_PARTICLES:
# If this is set, particles with a particle-ID equal to zero do not
# receive any SPH acceleration. This can be useful for idealized
# SPH tests, where these particles represent fixed "walls".
#
# - NOVISCOSITYLIMITER:
# If this is set, the code will not try to put an upper limit on
# the viscous force in case an implausibly high pair-wise viscous
# force (which may lead to a particle 'reflection' in case of poor
# timestepping) should arise. Note: For proper settings of the
# timestep parameters, this situation should not arise.
#
# - COMPUTE_POTENTIAL_ENERGY:
# When this option is set, the code will compute the gravitational
# potential energy each time a global statistics is computed. This
# can be useful for testing global energy conservation.
#
# - LONGIDS:
# If this is set, the code assumes that particle-IDs are stored as
# 64-bit long integers. This is only really needed if you want to
# go beyond ~2 billion particles.
#
# - ISOTHERM_EQS:
# This special option makes the gas behave like an isothermal gas
# with equation of state P = cs^2 * rho. The sound-speed cs is set by
# the thermal energy per unit mass in the intial conditions,
# i.e. cs^2=u. If the value for u is zero, then the initial gas
# temperature in the parameter file is used to define the sound speed
# according to cs^2 = 3/2 kT/mp, where mp is the proton mass.
#
# - ADAPTIVE_GRAVSOFT_FORGAS:
# When this option is set, the gravitational softening lengths used for
# gas particles is tied to their SPH smoothing length. This can be useful
# for dissipative collapse simulations. The option requires the setting
# of UNEQUALSOFTENINGS.
#
# - SELECTIVE_NO_GRAVITY:
# This can be used for special computations where one wants to
# exclude certain particle types from receiving gravitational
# forces. The particle types that are excluded in this fashion are
# specified by a bit mask, in the same as for the PLACEHIGHRESREGION
# option.
#
# - FORCETEST:
# This can be set to check the force accuracy of the code. The
# option needs to be set to a number between 0 and 1 (e.g. 0.01),
# which is taken to specify a random fraction of particles for
# which at each timestep forces by direct summation are
# computed. The normal tree-forces and the correct direct
# summation forces are collected in a file. Note that the
# simulation itself is unaffected by this option, but it will of
# course run much(!) slower, especially if
# FORCETEST*NumPart*NumPart >> NumPart. Note: Particle IDs must
# be set to numbers >=1 for this to work.
#
# - MAKEGLASS
# This option can be used to generate a glass-like particle
# configuration. The value assigned gives the particle load,
# which is initially generated as a Poisson sample and then
# evolved towards a glass with the sign of gravity reversed.

#-----------------------------------------------------------------------
#
# Brief guide to compile-time options of the code. More information
# can be found in the code documentation.
#
# - PERIODIC:
# Set this if you want to have periodic boundary conditions.
#
# - UNEQUALSOFTENINGS:
# Set this if you use particles with different gravitational
# softening lengths.
#
# - PEANOHILBERT:
# This is a tuning option. When set, the code will bring the
# particles after each domain decomposition into Peano-Hilbert
# order. This improves cache utilization and performance.
#
# - WALLCLOCK:
# If set, a wallclock timer is used by the code to measure internal
# time consumption (see cpu-log file). Otherwise, a timer that
# measures consumed processor ticks is used.
#
# - PMGRID:
# This enables the TreePM method, i.e. the long-range force is
# computed with a PM-algorithm, and the short range force with the
# tree. The parameter has to be set to the size of the mesh that
# should be used, (e.g. 64, 96, 128, etc). The mesh dimensions need
# not necessarily be a power of two. Note: If the simulation is
# not in a periodic box, then a FFT method for vacuum boundaries is
# employed, using an actual mesh with dimension twice(!) that
# specified by PMGRID.
#
# - PLACEHIGHRESREGION:
# If this option is set (will only work together with PMGRID), then
# the long range force is computed in two stages: One Fourier-grid
# is used to cover the whole simulation volume, allowing the
# computation of the longe-range force. A second Fourier mesh is
# placed on the region occupied by "high-resolution" particles,
# allowing the computation of an intermediate scale force. Finally,
# the force on short scales is computed with the tree. This
# procedure can be useful for "zoom-simulations", provided the
# majority of particles (the high-res particles) are occupying only
# a small fraction of the volume. To activate this option, the
# parameter needs to be set to an integer bit mask that encodes the
# particle types that make up the high-res particles.
# For example, if types 0, 1, and 4 form the high-res
# particles, set the parameter to PLACEHIGHRESREGION=19, because
# 2^0 + 2^1 + 2^4 = 19. The spatial region covered by the high-res
# grid is determined automatically from the initial conditions.
# Note: If a periodic box is used, the high-res zone may not intersect
# the box boundaries.
#
# - ENLARGEREGION:
# The spatial region covered by the high-res zone has a fixed size
# during the simulation, which initially is set to the smallest
# region that encompasses all high-res particles. Normally, the
# simulation will be interrupted if high-res particles leave this
# region in the course of the run. However, by setting this
# parameter to a value larger than one, the size of the high-res
# region can be expanded, providing a buffer region. For example,
# setting it to 1.4 will enlarge its side-length by 40% (it remains
# centered on the high-res particles). Hence, with this setting, the
# high-res region may expand or move by a limited amount.
# Note: If SYNCHRONIZATION is activated, the code will be able to
# continue even if high-res particles leave the initial high-res
# grid. In this case, the code will update the size and position of
# the grid that is placed onto the high-resolution region
# automatically. To prevent that this potentially happens every
# single PM step, one should nevertheless assign a value slightly
# larger than 1 to ENLARGEREGION.
#
# - ASMTH:
# This can be used to override the value assumed for the scale that
# defines the long-range/short-range force-split in the TreePM
# algorithm. The default value is 1.25, in mesh-cells.
#
# - RCUT:
# This can be used to override the maximum radius in which the
# short-range tree-force is evaluated (in case the TreePM algorithm
# is used). The default value is 4.5, given in mesh-cells.
#
# - DOUBLEPRECISION:
# This makes the code store and compute internal particle data in
# double precision. Note that output files are nevertheless written
# by converting the particle data to single precision.
#
# - DDOUBLEPRECISION_FFTW:
# If this is set, the code will use the double-precision version of
# FTTW, provided the latter has been explicitly installed with a
# "d" prefix, and NOTYPEPREFIX_FFTW is not set. Otherwise the
# single precision version ("s" prefix) is used.
#
# - SYNCHRONIZATION:
# When this is set, particles are kept in a binary hierarchy of
# timesteps and may only increase their timestep if the new
# timestep will put them into synchronization with the higher time
# level.
#
# - FLEXSTEPS:
# This is an alternative to SYNCHRONIZATION. Particle timesteps are
# here allowed to be integer multiples of the minimum timestep that
# occurs among the particles, which in turn is rounded down to the
# nearest power-of-two devision of the total simulated
# timespan. This option distributes particles more evenly over
# individual system timesteps, particularly once a simulation has
# run for a while, and may then result in a reduction of work-load
# imbalance losses.
#
# - PSEUDOSYMMETRIC:
# When this option is set, the code will try to "anticipate"
# timestep changes by extrapolating the change of the acceleration
# into the future. This can in certain idealized cases improve the
# long-term integration behaviour of periodic orbits, but should
# make little or no difference in most real-world applications. May
# only be used together with SYNCHRONIZATION.
#
# - NOSTOP_WHEN_BELOW_MINTIMESTEP:
# If this is activated, the code will not terminate when the
# timestep falls below the value of MinSizeTimestep specified in
# the parameterfile. This is useful for runs where one wants to
# enforce a constant timestep for all particles. This can be done
# by activating this option, and by setting MinSizeTimestep and
# MaxSizeTimestep to an equal value.
#
# - NOPMSTEPADJUSTMENT:
# When this is set, the long-range timestep for the PM-force
# computation (when the TreePM algorithm is used) is always
# determined by MaxSizeTimeStep. Otherwise, it is determined by
# the MaxRMSDisplacement parameter, or MaxSizeTimeStep, whichever
# gives the smaller step.
#
# - HAVE_HDF5:
# If this is set, the code will be compiled with support for input
# and output in the HDF5 format. You need to have the HDF5
# libraries and headers installed on your computer for this option
# to work. The HDF5 format can then be selected as format "3" in
# Gadget's parameterfile.
#
# - OUTPUTPOTENTIAL:
# This will make the code compute gravitational potentials for
# all particles each time a snapshot file is generated. The values
# are then included in the snapshot file. Note that the computation
# of the values of the gravitational potential costs additional CPU.
#
# - OUTPUTACCELERATION:
# This will include the physical acceleration of each particle in
# snapshot files.
#
# - OUTPUTCHANGEOFENTROPY:
# This will include the rate of change of entropy of gas particles
# in snapshot files.
#
# - OUTPUTTIMESTEP:
# This will include the current timesteps of all particles in the
# snapshot files.
#
# - NOGRAVITY
# This switches off gravity. Useful only for pure SPH simulations
# in non-expanding space.
#
# - NOTREERND:
# If this is not set, the tree construction will succeed even when
# there are a few particles at identical locations. This is done by
# `rerouting' particles once the node-size has fallen below 1.0e-3
# of the softening length. When this option is activated, this will
# be surpressed and the tree construction will always fail if there
# are particles at extremely close coordinates.
#
# - NOTYPEPREFIX_FFTW:
# This is an option that signals that FFTW has been compiled
# without the type-prefix option, i.e. no leading "d" or "s"
# characters are used to access the library.
#
# - LONG_X/Y/Z:
# These options can be used together with PERIODIC and NOGRAVITY only.
# When set, the options define numerical factors that can be used to
# distorts the periodic simulation cube into a parallelepiped of
# arbitrary aspect ratio. This can be useful for idealized SPH tests.
#
# - TWODIMS:
# This effectively switches of one dimension in SPH, i.e. the code
# follows only 2d hydrodynamics in the xy-, yz-, or xz-plane. This
# only works with NOGRAVITY, and if all coordinates of the third
# axis are exactly equal. Can be useful for idealized SPH tests.
#
# - SPH_BND_PARTICLES:
# If this is set, particles with a particle-ID equal to zero do not
# receive any SPH acceleration. This can be useful for idealized
# SPH tests, where these particles represent fixed "walls".
#
# - NOVISCOSITYLIMITER:
# If this is set, the code will not try to put an upper limit on
# the viscous force in case an implausibly high pair-wise viscous
# force (which may lead to a particle 'reflection' in case of poor
# timestepping) should arise. Note: For proper settings of the
# timestep parameters, this situation should not arise.
#
# - COMPUTE_POTENTIAL_ENERGY:
# When this option is set, the code will compute the gravitational
# potential energy each time a global statistics is computed. This
# can be useful for testing global energy conservation.
#
# - LONGIDS:
# If this is set, the code assumes that particle-IDs are stored as
# 64-bit long integers. This is only really needed if you want to
# go beyond ~2 billion particles.
#
# - ISOTHERM_EQS:
# This special option makes the gas behave like an isothermal gas
# with equation of state P = cs^2 * rho. The sound-speed cs is set by
# the thermal energy per unit mass in the intial conditions,
# i.e. cs^2=u. If the value for u is zero, then the initial gas
# temperature in the parameter file is used to define the sound speed
# according to cs^2 = 3/2 kT/mp, where mp is the proton mass.
#
# - ADAPTIVE_GRAVSOFT_FORGAS:
# When this option is set, the gravitational softening lengths used for
# gas particles is tied to their SPH smoothing length. This can be useful
# for dissipative collapse simulations. The option requires the setting
# of UNEQUALSOFTENINGS.
#
# - SELECTIVE_NO_GRAVITY:
# This can be used for special computations where one wants to
# exclude certain particle types from receiving gravitational
# forces. The particle types that are excluded in this fashion are
# specified by a bit mask, in the same as for the PLACEHIGHRESREGION
# option.
#
# - FORCETEST:
# This can be set to check the force accuracy of the code. The
# option needs to be set to a number between 0 and 1 (e.g. 0.01),
# which is taken to specify a random fraction of particles for
# which at each timestep forces by direct summation are
# computed. The normal tree-forces and the correct direct
# summation forces are collected in a file. Note that the
# simulation itself is unaffected by this option, but it will of
# course run much(!) slower, especially if
# FORCETEST*NumPart*NumPart >> NumPart. Note: Particle IDs must
# be set to numbers >=1 for this to work.
#
# - MAKEGLASS
# This option can be used to generate a glass-like particle
# configuration. The value assigned gives the particle load,
# which is initially generated as a Poisson sample and then
# evolved towards a glass with the sign of gravity reversed.
