v6.08.113 SSND113 - SIMU_POINT_MAT in large deformations, imposed transformation gradient

Summary:

On a problem reduced to the material point, for behavior VISC_ISOT_TRAC in large deformations of type SIMO_MIEHE, we compare the solution obtained by imposing a deformation tensor with that obtained by imposing the corresponding transformation gradient. This test validates this feature in SIMU_POINT_MAT

Modeling A: this modeling is used as a reference, deformations imposed with SIMU_POINT_MAT.

B modeling: this modeling uses a transformation gradient imposed with SIMU_POINT_MAT.
