fix_modify AtC fix_flux command¶
Syntax¶
fix_modify <AtC fixID> fix_flux <field> <face_set> <value|function>
AtC fixID = ID of fix atc instance
fix_flux = name of the AtC sub-command
field = field kind name valid for type of physics: temperature or electron_temperature
face_set = name of set of element faces
value or function = value or name of function followed by its parameters
Examples¶
fix_modify AtC fix_flux temperature faceSet 10.0
Description¶
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.
Restrictions¶
Only normal fluxes (Neumann data) can be prescribed.
Default¶
None.
