fix_modify AtC source command

Syntax

fix_modify <AtC fixID> source <field> <element_set> <value|function>

  • AtC fixID = ID of fix atc instance

  • source = name of the AtC sub-command

  • field = field kind name valid for type of physics: temperature or electron_temperature

  • element_set = name of set of elements

  • value or function = value or name of function followed by its parameters

Examples

fix_modify AtC source temperature middle temporal_ramp 10.0 0.0

Description

Add domain sources to the mesh. The units are consistent with LAMMPS’s units for mass, length and time and are defined by the PDE being solved, e.g. for thermal transfer the balance equation is for energy and source is energy per time.

Restrictions

The keyword all is reserved and thus not available as element_set name.

Default

None.
