v3.03.123 SSLS123 - Sphere under uniform external pressure

Summary:

The case of the sphere under uniform external pressure in linear elasticity is treated, which makes it possible to assess the quality of the modeling of pressure forces.

The values tested are the radial displacements at the points of intersection with the axes.
