7. D modeling

7.1. Characteristics of modeling

3D modeling:

Number of nodes:	\(27\)
Number of stitches:	\(8\) HEXA8

The D modeling uses AFFE_CHAR_MECA, the solver GCR, and the pre-conditioner LDLT_SP. The distribution by group of elements is used for elementary calculations. A resolution is carried out with MECA_STATIQUE (by applying pressure) then a resolution with STAT_NON_LINE (by applying a subsequent pressure). The second resolution makes it possible to validate the correct functioning of the distributed matrix for a non-symmetric matrix.
