Lagrangian Phase Boundary Conditions

The “boundary conditions” for a Lagrangian phase describe how particles behave when they impinge on a boundary.

This behavior varies according to the boundary interaction mode and whatever conditions and values are required at the boundary by the interaction mode and the Lagrangian phase models. For some boundary types, this behavior follows obvious default modes with no additional user input. For other boundaries, however, some modeling is sometimes required, and so boundary conditions for each Lagrangian phase must be specified. You can choose to specify:

Phase models that are associated with boundary interaction modes are:

When you work with the Discrete Element Method (DEM), a special DEM mode is available.
