Description:

<P>
Perform updates of position and orientation, but not velocity or
angular momentum for atoms in the group each timestep. In other
words, the force and torque on the atoms is ignored and their velocity
and angular momentum are not updated. The atom velocities and
angularm momenta are used to update their positions and orientation.
</P>
<P>
This is useful as an implicit time integrator for Fast Lubrication
Dynamics, since the velocity and angular momentum are updated by the

pair_style lubricuteU

command.

This fix is part of the ASPHERE package. It is only enabled if LAMMPS
was built with that package. See the

This fix requires that atoms store torque and angular momementum and a
quaternion as defined by the
<A

"atom_style.html"
>
atom_style ellipsoid
</A>
command.
</P>
<P>
All particles in the group must be finite-size. They cannot be point
particles, but they can be aspherical or spherical as defined by their
shape attribute.
