Benchmark solution
=====================

Benchmark solution
---------------------

The reference solution is taken in non-regression on a fine quadratic 3D calculation: all the tests are therefore of type AUTRE_ASTER for displacements and constraints.

In flexure, we test:


* Move DZ to node I


* von Mises constraints SIEQ_NOEU, component VMIS at nodes C, E, and G

In traction, we test:


* Move DX to Node I


* von Mises constraints SIEQ_NOEU, component VMIS at nodes C, E, and G
