decrease in potential energy when atoms move in the direction of the
added force.
The "fix_modify"_fix_modify.html {virial} option is supported by this
fix to add the contribution due to the interaction between
atoms and each wall to the system's virial as part of "thermodynamic
output"_thermo_style.html. The default is {virial no}
The "fix_modify"_fix_modify.html {respa} option is supported by this
fix. This allows to set at which level of the "r-RESPA"_run_style.html
integrator the fix is adding its forces. Default is the outermost
