v1.01.392 ZZZZ392 — Validation of the mode_meca concept from CREA_RESU for COMB_SISM_MODAL/MODE_CORR

Summary:

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

It aims to validate the AXE keyword from CREA_RESU/AFFE. The purpose of this keyword is to be able to provide the MODE_CORR operand from COMB_SISM_MODAL with a mode_meca concept from CREA_RESU instead of a mode_meca concept from MODE_STATIQUE.

Modeling A:

The principle of the test is as follows: using the CREA_CHAMP operator, we extract the displacement field from a MODE_STATIQUE mode_mecaissu concept (there are 3 order numbers each corresponding to a direction of space). We create a mode_meca concept from the field extracted with CREA_RESU, by entering the AXEde AFFE keyword. It takes the value X for the first order number, Y for the second, and Z for the third.

For the 3 directions of space, the COMB_SISM_MODAL operator is called twice, once by entering the concept from MODE_STATIQUE to MODE_CORR, this calculation being used as a reference and a second time with the concept from CREA_RESU. We check that we get the same results as in the first one.

It should be noted that the second calculations do not work without entering the AXE keyword of CREA_RESU/AFFE.
