7. F modeling#
This modeling is identical to modeling E, which tests the use of the automatic method of managing the time step with the parameter MODE_CALCUL_TPLUS = ITER_NEWTON.
7.1. Modeling characteristics and meshes#
The characteristics of this modeling are identical to those used for modeling \(A\).
7.2. Tested sizes and results#
We test the difference between the force-displacement curves calculated with the two methods (IMPLEX and Newton). The values tested are differences in effort between the two methods at different times.
