Elastic parallel computation of a full diabolo subjected to a thermal loading

In this example the computation of an elastic diabolo subjected to a sinusoidal thermal loading is carried out. This modelization is similar to perf008. Its goal is to present parallelism possiblities in Code_Aster.

Modelizations

Name of the use test perf010
Code version 12
Type of analysis Elastic computation
Material behaviour Elastic
Geometric behaviour Small displacements
Dominant type of mesh Hexahedron
