fix mdi/engine command¶
fix ID group-ID mdi/engine
ID, group-ID are documented in fix command
mdi/engine = style name of this fix command
fix 1 all mdi/engine
This fix is used along with the mdi/engine command to enable LAMMPS to use the MDI Library to run as an MDI engine. The fix provides hooks that enable MDI driver codes to communicate with LAMMPS at various points within a LAMMPS timestep.
It is not generally necessary to add this fix to a LAMMPS input file, even when using the mdi/engine command. If the mdi/engine command is executed and this fix is not present, it will automatically be added and applied as a new fix for all atoms for the duration of the command. Thus it is only necessary to add this fix to an input file when you want to modify the group-ID or the ordering of this fix relative to other fixes in the input script.
This command is part of the MDI package. It is only enabled if LAMMPS was built with that package. See the Build package page for more info.
