**v1.01.253** ZZZZ253 — Mechanical nonlinear calculation with mesh change
=================================================================================

**Summary:**

This test has no physical meaning, it is essentially a computer test.

Modeling A:

In this modeling, we want to check the possibility of performing a mechanical calculation by starting it on one mesh and ending it on another.

The reference results are given by the same calculation performed only on the first mesh as well as only on the second mesh.

The mesh change is done using the PROJ_CHAMP command with the COLLOCATION method.

This documentation is deliberately brief.
