v3.03.105 SSLS105 - Double pinched hemisphere

Summary:

The case of the doubly pinched hemisphere is treated in linear elasticity, which makes it possible to evaluate the quality of the plane facets for the representation of a deep shell.

The values tested are the arrows at the points of application of the forces.
