5. Summary of results

At the end of this test (modeling A), it appears that the numerical solution coincides remarkably with the analytical solution. However, it will be noted that the high nonlinearity due to large rotations requires discretization in relatively fine time, without being detrimental to precision since, unlike an incremental behavior relationship, errors do not accumulate from one step of time to the other.

Modeling B validates the dependence of pressure on the initial geometry.
