D modeling
==============

The D 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 (C modeling).


Characteristics of modeling
-----------------------------------

1373 shell elements DKT

1373 grid items GRILLE_MEMBRANE

Modeling a quarter of the hemisphere in TRIA3.


Characteristics of the mesh
----------------------------

Number of knots: 734

Number of meshes and types: 2746 TRIA3


Tested sizes and results
------------------------------

We compare the displacement values with those calculated by the Python loop (modeling :math:`C`)
