v1.01.266 ZZZZ266 - Validating the COOR_ELGA option from CALC_CHAM_ELEM

Summary:

This test validates in \(\mathrm{2D}\) and \(\mathrm{3D}\) the calculation of the coordinates of the Gauss point using the command CALC_CHAM_ELEM.

Modeling A:

The principle is to read the mesh with command LIRE_MAILLAGE, assign a model using command AFFE_MODELE and calculate the coordinates of the Gauss point using option COOR_ELGA of command CALC_CHAM_ELEM. There is therefore no uncertainty about the results to be obtained:

• For a discrete type « POI1 » the Gauss point is at the same position as the node.

• For a discrete type « SEG2 » the Gauss point is in the middle of the segment.

Modeling B:

It is the same approach but for different models:

• For elements with plane deformations.

• For elements with plane constraints.

• For edge elements in three-dimensional modeling (faces and segments).

• For elements with 2D modeling_ FLUIDE (U_P and U_P_ PHI)
