u3.13.12 Modeling D_ PLAN_ABSO

Summary:

This document describes for modeling D_ PLAN_ABSO:

• the degrees of freedom carried by the finite elements that support modeling,

• the related support meshes,

• the loads supported,

• non-linear possibilities,

• test cases implementing modeling.

The D_ PLAN_ABSO modeling (Phenomenon: mechanical) corresponds to finite elements whose support cells are linear. They make it possible to take into account the absorbent boundary condition of sections of solids, studied in plane deformations.
