/MAT/LAW51 - Iform = 3: Outlet Boundaries for Multi-Material Law

Description

This formulation handles Outlet conditions for Multi-Material ALE domain (formulation: Iform = 0, 1, 10 or 11).

Initial state must be provided for each sub-material present in adjacent ALE domain.

hmtoggle_plus1Comments
1.Initial volumetric fractions enable the sharing of elementary volume within the three different materials.

For each material, must be defined between 0 and 1.

Sum of initial volumetric fractions mat51_initial_vol_sum must be equal to 1.

2.It is recommended to build boundary layer elements normal to the direction of the modeling flow.
3.Outlet element state is computed using initial values and affected quantities from adjacent element.
