The aim of this test case is to validate the following functions:
The simulation results of SimScale were compared to the results presented in [SSNV104]. The meshes used in (A) and (C) were created with the automatic-tetrahedralization meshing algorithm on the SimScale platform. The additional meshes in (B) and (D) were locally meshed with refinements.
Only one eighth of each of the two spheres (with radius R = 50 mm) is used for the analysis due to the symmetry of the problem.
