thermo command
Syntax
thermo N
N = output thermodynamics every N timesteps
N can be a variable (see below)
Examples
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 thermo_style and thermo_modify commands.
Instead of a numeric value, N can be specified as an equal-style 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 equal-style variables, as examples of useful functions to use in this context. Other similar math functions could easily be added as options for equal-style variables.
For example, the following commands will output thermodynamic info at timesteps 0, 10, 20, 30, 100, 200, 300, 1000, 2000, etc:
variable s equal logfreq(10,3,10)
thermo v_s
Restrictions
none
Default
thermo 0
