**v1.01.144** ZZZZ144 - Validation of LIAISON_SOLIDE and LIAISON_RBE3
====================================================================

**Summary:**

This test validates LIAISON_SOLIDE and LIAISON_RBE3 in HPC.

We model a cylinder, embedded on one end, subjected to an imposed pressure, part of which is rigidified by a LIAISON_SOLIDE. A torque is applied to the other end using a discrete connected to the body by a LIAISON_RBE3.

In this way, numerous Lagrange multipliers are used to impose kinematic relationships.

The test case has 3 models:


* modeling A: classical parallelism, solver MUMPS


* B modeling: hpc parallelism, solver MUMPS


* C modeling: hpc parallelism, solver PETSC + LDLT_SP

The displacement of the discrete is compared to the sequential result.

This documentation is deliberately brief.
