Voluminal Paving Stone Subjected to Harmonic Pressure
Overview
The aim of this test case is to validate the following functions:
- Harmonic analysis
- Harmonic pressure
The simulation results of SimScale were compared to the numerical results in [SDLV124]. The mesh used in case (A) was obtained from Code_Aster.
