**v1.01.297** ZZZZ297 — Validation of the LIAISON_PROJ keyword from the AFFE_CHAR_MECA command
==========================================================================================

**Summary:**

The objective is to test and validate the possibilities of the LIAISON_PROJ keyword in the affe_char_meca command. LIAISON_PROJ allows you to define linear relationships between the nodes of the same model. The coefficients of the linear relationships are determined using the PROJ_CHAMP command, which returns a concept that corresponds to the matrix of influence coefficients determined from the shape functions of the elements.

The test cases validate several configurations:

• relationships between groups of solid cells: volume master cells, volume slave cells: modeling A;

• relationships between groups of solid cells and surface cells: volume master cells, surface slave cells: B modeling;

• relationships between groups of solid cells and line cells: volume master cells, linear slave cells: C modeling;

• relationships between groups of surface cells: surface master cells, surface slave cells, with and without eccentricity: D and E models;

• relationships between groups of surface and line cells: surface master cells, linear slave cells with eccentricity: F modeling.
