v1.01.108 ZZZZ108 - Code_Aster- MISS3D interface test

Summary:

This test makes it possible to model in harmonic and transitory linear dynamics a structure such as a building bundle model (discrete elements and beams) completed at its base of solid and surface elements.

Its interest is to test Code_Aster commands specific to soil-structure interaction in order to interface with the software MISS3D (ECP - LMSSMat).

In this test, the movement to control points located in the ground and added to the modeling of the structure by Code_Aster is also tested by post-processing.

Finally, it is verified that the accelerograms can be given directly on a frequency basis by reproducing the calculation for which they are given on a time basis.
