Applying MPM Boundary Conditions

In MPM, there are two types of boundary conditions. You can apply conditions to the grid or directly to particles.

Grid-Based Boundary Conditions

To apply boundary conditions on the grid, you first select nodes using:

This block has replaced several deprecated boundary condition blocks. Within the GridBC block, you can set the following conditions on the selected nodes:

Sometimes you need to apply boundary conditions on the grid that move as the object moves through the grid. The required moving, grid based conditions can be applied by using rigid particles (with SetDirection = 0 to 7).

Particle-Based Boundary Conditions

To apply boundary conditions to particles, you first select particles using:

This block has replaced several deprecated boundary condition blocks. Within the ParticleBC block, you can set the following conditions on the selected particles:
