			<H3>9. Errors
			</H3>
			<P>This section describes the various kinds of errors you can encounter
			when using LAMMPS.
			</P>

			<A NAME = "9_1"></A><H4>9.1 Common problems
			</H4>
			<P>If two LAMMPS runs do not produce the same answer on different
			machines or different numbers of processors, this is typically not a
			bug. In theory you should get identical answers on any number of
			processors and on any machine. In practice, numerical round-off can
			cause slight differences and eventual divergence of molecular dynamics
			phase space trajectories within a few 100s or few 1000s of timesteps.
			However, the statistical properties of the two runs (e.g. average
			energy or temperature) should still be the same.
			</P>
			<P>If the <A HREF = "velocity.html">velocity</A> command is used to set initial atom
			velocities, a particular atom can be assigned a different velocity
			when the problem on different machines. Obviously, this means the
			phase space trajectories of the two simulations will rapidly diverge.
			See the discussion of the <I>loop</I> option in the
			<A HREF = "velocity.html">velocity</A> command for details.
			</P>
			<P>A LAMMPS simulation typically has two stages, setup and run. Most
			LAMMPS errors are detected at setup time; others like a bond
			stretching too far may not occur until the middle of a run.
			</P>
			<P>LAMMPS tries to flag errors and print informative error messages so
			you can fix the problem. Of course LAMMPS cannot figure out your
			physics mistakes, like choosing too big a timestep, specifying invalid
			force field coefficients, or putting 2 atoms on top of each other! If
			you find errors that LAMMPS doesn't catch that you think it should
			flag, please send an email to the
			<A HREF = "http://lammps.sandia.gov/authors.html">developers</A>.
			</P>
			<P>If you get an error message about an invalid command in your input
			script, you can determine what command is causing the problem by
			looking in the log.lammps file or using the <A HREF = "echo.html">echo command</A>
			to see it on the screen. For a given command, LAMMPS expects certain
			arguments in a specified order. If you mess this up, LAMMPS will
			often flag the error, but it may read a bogus argument and assign a
			value that is valid, but not what you wanted. E.g. trying to read the
			string "abc" as an integer value and assigning the associated variable
			a value of 0.
			</P>
			<P>Generally, LAMMPS will print a message to the screen and exit
			gracefully when it encounters a fatal error. Sometimes it will print
			a WARNING and continue on; you can decide if the WARNING is important
			or not. If LAMMPS crashes or hangs without spitting out an error
			message first then it could be a bug (see <A HREF = "#9_2">this section</A>) or one
			of the following cases:
			</P>
			<P>LAMMPS runs in the available memory a processor allows to be
			allocated. Most reasonable MD runs are compute limited, not memory
			limited, so this shouldn't be a bottleneck on most platforms. Almost
			all large memory allocations in the code are done via C-style malloc's
			which will generate an error message if you run out of memory.
			Smaller chunks of memory are allocated via C++ "new" statements. If
			you are unlucky you could run out of memory just when one of these
			small requests is made, in which case the code will crash or hang (in
			parallel), since LAMMPS doesn't trap on those errors.
			</P>
			<P>Illegal arithmetic can cause LAMMPS to run slow or crash. This is
			typically due to invalid physics and numerics that your simulation is
			computing. If you see wild thermodynamic values or NaN values in your
			LAMMPS output, something is wrong with your simulation.
			</P>
			<P>In parallel, one way LAMMPS can hang is due to how different MPI
			implementations handle buffering of messages. If the code hangs
			without an error message, it may be that you need to specify an MPI
			setting or two (usually via an environment variable) to enable
			buffering or boost the sizes of messages that can be buffered.
			</P>

			<A NAME = "9_2"></A><H4>9.2 Reporting bugs
			</H4>
			<P>If you are confident that you have found a bug in LAMMPS, please send
			an email to the <A HREF = "http://lammps.sandia.gov/authors.html">developers</A>.
			</P>
			<P>First, check the "New features and bug fixes" section of the <A HREF = "http://lammps.sandia.gov">LAMMPS
			WWW site</A> to see if the bug has already been reported or fixed.
			</P>
			<P>If not, the most useful thing you can do for us is to isolate the
			problem. Run it on the smallest number of atoms and fewest number of
			processors and with the simplest input script that reproduces the bug.
			</P>
			<P>In your email, describe the problem and any ideas you have as to what
			is causing it or where in the code the problem might be. We'll
			request your input script and data files if necessary.
			</P>
			<HR>

			<H4><A NAME = "9_3"></A>9.3 Error & warning Messages
			</H4>
			<P>These are two alphabetic lists of the <A HREF = "#error">ERROR</A> and
			<A HREF = "#warn">WARNING</A> messages LAMMPS prints out and the reason why. If the
			explanation here is not sufficient, the documentation for the
			offending command may help. Grepping the source files for the text of
			the error message and staring at the source code and comments is also
			not a bad idea! Note that sometimes the same message can be printed
			from multiple places in the code.

			<DT><I>Fix recenter should come after all other integration fixes</I>

			<DD>Other fixes may change the position of the center-of-mass, so
			fix recenter should come last.

			<DT><I>Fix wall/reflect should come after all other integration fixes</I>

			<DD>This is because other integration fixes may alter the coordinates
			of an atom, so you want to reflect it back into the box only after
			the other fixes have made their adjustments.

			<DT><I>Group for fix_modify temp != fix group</I>

			<DD>The fix_modify command is specifying a temperature computation that
			computes a temperature on a different group of atoms than the fix
			itself operates on. This is probably not what you want to do.

			<DT><I>Less insertions than requested</I>

			<DD>Less atom insertions occurred on this timestep due to the fix insert

			minimization.

			<DT><I>Resetting unit_style to restart file value</I>

			of the restart file.

			<DT><I>Restart file used different # of processors</I>

			<DD>The restart file was written out by a LAMMPS simulation running on a

			you ran on the same # of processors.

			<DT><I>Restart file used different newton pair setting</I>

			<DD>The restart file was written out by a LAMMPS simulation running with a
			different value of the newton pair setting. The new simulation will
			use the value from the input script.

			<DT><I>Restart file version does not match LAMMPS version</I>

			<DD>The version of LAMMPS that wrote the restart file does not match the
			version of LAMMPS that is reading the restart file. Generally this
			shouldn't be a problem, since restart file formats won't change very

			<DD>You specified an inner cutoff for a Coulombic table that is longer
			than the global cutoff. Probably not what you wanted.

			<DT><I>Temperature for NPH is not for group all</I>

			<DD>User-assigned temperature to NPH fix does not compute temperature for
			all atoms. Since NPH computes a global pressure, the kinetic energy
			contribution from the temperature is assumed to also be for all atoms.
			Thus the pressure used by NPH could be inaccurate.

			<DT><I>Temperature for NPT is not for group all</I>

			<DD>User-assigned temperature to NPT fix does not compute temperature for
			all atoms. Since NPT computes a global pressure, the kinetic energy

			Thus the pressure used by NPT could be inaccurate.

			<DT><I>Temperature for thermo pressure is not for group all</I>

			<DD>User-assigned temperature to thermo via the thermo_modify command does
			not compute temperature for all atoms. Since thermo computes a global
			pressure, the kinetic energy contribution from the temperature is
			assumed to also be for all atoms. Thus the pressure printed by thermo
			could be inaccurate.

			<DT><I>Using compute temp/deform with inconsistent fix deform remap option</I>

			<DD>Fix nvt/sllod assumes deforming atoms have a velocity profile provided
			by "remap v" or "remap none" as a fix deform option.

			<DT><I>Using compute temp/deform with no fix deform defined</I>

			<DD>Self-explanatory.

			<DT><I>Using pair tail corrections with nonperiodic system</I>

			<DD>This is probably a bogus thing to do, since tail corrections are
			computed by integrating the density of a periodic system out to
			infinity.

			<DT><I>Variable equal keyword used with non-current thermo</I>

			<DD>The evaluation of the variable may be inaccurate as a result.
