Eigenfrequencies of a thick cylindrical ring¶
The aim of this test case is to validate the following functions:
- Modal (frequency) solver
The simulation results of SimScale were compared to the results presented in [SDLS109]. Two of the mesh cases were considered; linear tetrahedral and linear hexahedrals.
