In this project the functionality of the transient thermomechanical solver with nonlinear material behavior on SimScale platform is validated. The geometry used was a perforated plate as shown in figure below.
Four mesh types were considered; linear and quadratic tetrahedrals and hexahedrals. The hexahedral meshes were created locally and than uploaded to SimScale platform. Whereas, the tetrahedral meshes were created using automatic tetrahedralization on SimScale platform. The quadratic tetrahedral and hexahedral meshes are shown in the figures below.
Transient thermostructural analysis was performed. Node nO was constrained in all directions whereas node nB and nC were constrained in x-z and x direction respectively. Node nA was given zero temperature boundary condition. Faces ADHE and BCGF were given pressure of 1 Pa. Furthermore all the faces were given specific surface heat flux. The figures below show the x-displacement and temperature contour plots.
