3. B modeling#
B modeling tests the AXE feature of the GRILLE option from AFFE_CARA_ELEM, which allows the reinforcements to be oriented directly by Code_Aster. The results using Python loops are used to provide the reference solution.
3.1. Characteristics of modeling#
1373 shell elements DKT
1373 grid items GRILLE_MEMBRANE
Modeling a quarter of the hemisphere in TRIA3.
3.2. Characteristics of the mesh#
Number of knots: 734
Number of meshes and types: 2746 TRIA3
3.3. Tested sizes and results#
We compare the displacement values with those calculated by the Python loop (modeling \(A\)).
