+Syntax

+
+.. parsed-literal::
+
+   thermo N
+
+* N = output thermodynamics every N timesteps
+* N can be a variable (see below)

+Examples

+.. parsed-literal::
+
+   thermo 100
+
+Description
+"""""""""""
+
+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.
+
+The content and format of what is printed is controlled by the
+:doc:`thermo_style <thermo_style>` and
+:doc:`thermo_modify <thermo_modify>` commands.
+
+Instead of a numeric value, N can be specifed as an :doc:`equal-style variable <variable>`, 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 :doc:`equal-style variables <variable>`, as examples of useful functions to use in
+this context.  Other similar math functions could easily be added as
+options for :doc:`equal-style variables <variable>`.
+
+For example, the following commands will output thermodynamic info at
+timesteps 0,10,20,30,100,200,300,1000,2000,etc:
+
+.. parsed-literal::
+
+   variable	s equal logfreq(10,3,10)
+   thermo	        v_s
