Main Help → All Commands → MPM Grid and Material Points → GridThickness
The GridThickness
command sets the thickness for planar 2D MPM grids:
GridThickness (thick)
where (thick)
is the grid thickness in length units.
GridThickness
is optional in single-material mode because
thickness can be set when defining material point regions
and when defining cracks. If used, however, all
material points and cracks will default to this grid thickness. You can enter
different values, although it is not recommended (and may change the physics in multimaterial simulations). A warning is printed in the output if a crack thickness does not match the grid thickness. Currently no warning is given if material points have a different thickness.GridThickness
command is only allowed for MPM analyses.
