<P>Compute and print thermodynamic info (e.g. temperature, energy,
|
|
|
|
|
pressure) on timesteps that are a multiple of N and at the beginning
|
|
|
|
|
and end of a simulation. A value of 0 will only print thermodynamics
|
|
|
|
|
at the beginning and end.

|
|
|
<P>The content and format of what is printed is controlled by the

|
<P>Instead of a numeric value, N can be specifed as an <A HREF = "variable.html">equal-style
|
|
|
|
|
variable</A>, which should be specified as v_name, where
|
|
|
|
|
name is the variable name. In this case, the variable is evaluated at
|
|
|
|
|
the beginning of a run to determine the next timestep at which
|
|
|
|
|
thermodynamic info will be written out. On that timestep, the
|
|
|
|
|
variable will be evaluated again to determine the next timestep, etc.
|
|
|
|
|
Thus the variable should return timestep values. See the stagger()
|
|
|
|
|
and logfreq() and stride() math functions for <A HREF = "variable.html">equal-style
|
|
|
|
|
variables</A>, as examples of useful functions to use in
|
|
|
|
|
this context. Other similar math functions could easily be added as
|
|
|
|
|
options for <A HREF = "variable.html">equal-style variables</A>.
