description</a></h2>
Command for fixing normal fluxes e.g. heat_flux. This command only prescribes the normal component of the physical flux, e.g. heat (energy) flux. The units are in AtC units, i.e. derived from the LAMMPS length, time, and mass scales. <h2><a class="anchor" name="restrictions">
restrictions</a></h2>
Only normal fluxes (Neumann data) can be prescribed. <h2><a class="anchor" name="related">
