Description:
</B>
</P>
<P>
Modify the parameters of a previously defined temperature method.
This can either be the default temperature defined by LAMMPS (ID =
<I>
default
</I>
) or a user-defined temperature created by using the
<A
HREF =
"temperature.html"
>
temperature
</A>
command.
</P>
<P>
The
<I>
extra
</I>
keyword refers to how many degrees-of-freedom are
subtracted (typically from 3N) as a normalizing factor in the
temperature computation. The default is 3 which is a correction
factor for an ensemble of velocities with zero total linear momentum.
