The aim of this test case is to validate the following functions:
The simulation results of SimScale were compared to the numerical results presented in case B of [SDNV103]. In addition to the quadratic mesh consisting of prisms and hexahedrals described in [SDNV103], the linear hexahedral mesh was also used.
