To allow custom tasks to inject particles, the reservoir needs to be seeded with enough material points for the injection process. The command to fill the reservoir is:
Fill (num),(matid),<(lx)>,<(ly)>,<(lz)>
where
(num)
is the number of material points to put into the reservoir.(matid)
is the material ID for a previously defined material.(lx)
, (ly)
, and (lz)
optionally specify the size of the material point in length units. If these optional parameters are not provided, the material points will use the default size for the simulation.More details on using and filling the material point reservoir are on the OSUPdocs wiki.
