Main Help → All Commands → MPM Boundary Conditions → GridBC
Velocity, temperature, and concentration conditions are applied to nodes in the background MPM mesh by using a series of GridBC
blocks. Each blocks selects some nodes using one subordinate shape command. The format for the block is:
GridBC (one shape command, which can be nested) (any number ofVelocity
,Temperature
,Concentration
, orPorePressure
commands) EndGridBC
All nodes within the one shape can be assigned velocity, temperature, or concentration conditions by using commands between GridBC
and EndGridBC
.
GridBC
command is only allowed for MPM analyses.
