/MAT/LAW51 (Iform = 3) (Obsolete)

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

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

Field	Contents	SI Unit Example
`mat_ID`	Material identifier (Integer, maximum 10 digits)
`mat_title`	Material title (Character, maximum 100 characters)
`I`_form	Formulation flag (Integer)
$α_{0}^{mat_i}$ $α_{0}^{mat_i}$	Initial volumetric fraction 1 (Real)
$ρ_{0}^{mat_i}$ $ρ_{0}^{mat_i}$	Initial density (Real)	$[\frac{kg}{m^{3}}]$ $[\frac{kg}{m^{3}}]$
$E_{0}^{m a t_ i}$ $E_{0}^{m a t_ i}$	Initial energy per unit volume (Real)	$[\frac{J}{m^{3}}]$ $[\frac{J}{m^{3}}]$
$P_{0}^{m a t_ i}$ $P_{0}^{m a t_ i}$	Initial pressure (Real)	$[Pa]$ $[Pa]$

Initial volumetric fractions enable the sharing of elementary volume within the three different materials.
For each material, $α_{0}^{mat_ i}$ $α_{0}^{mat_ i}$ must be defined between 0 and 1.

Sum of initial volumetric fractions $\sum_{i = 1}^{3} α_{0}^{mat _ i}$ $\sum_{i = 1}^{3} α_{0}^{mat _ i}$ must be equal to 1.
It is recommended to build boundary layer elements normal to the direction of the modeling flow.
Outlet element state is computed using initial values and affected quantities from adjacent element.
