example, a value of 100.0 means to relax the temperature in a timespan
of (roughly) 100 time units (tau or fmsec or psec - see the

<P>The way that Langevin thermostatting operates is explained on the <A HREF = "fix_langevin.html">fix
langevin</A> doc page. If you wish to simply viscously
damp the rotational motion without thermostatting, you can set
<I>Tstart</I> and <I>Tstop</I> to 0.0, which means only the viscous drag term in
the Langevin thermostat will be applied. See the discussion on the
<A HREF = "doc/fix_viscous.html">fix viscous</A> doc page for details.

<P>IMPORTANT NOTE: When the <I>langevin</I> keyword is used with fix rigid
versus fix rigid/small, different dynamics will result for parallel
