12. L modeling

12.1. Characteristics of modeling

3D modeling_ HHO linear: 2269 tetrahedral volume elements: TETRA8.

The families of sliding systems are of the octahedral type. The structure contains 10 grains generated by a Python procedure based on Voronoi cells. Each of the grains corresponds to 3 Euler angles which define the orientations of the sliding systems.

12.2. Tested sizes and results

Comparison of the results obtained with*Code_Aster* at the last calculated moment. The errors are greater for this modeling because the coordinates of the Gauss point are slightly different from the reference ones (the quadrature is different).
