The meshes used in (A) and (B) were created with the Standard mesher tool on the SimScale platform and the meshes used in (C) and (D) were meshed locally and exported to SimScale. Details can be found in Table 1:
Number of nodes
1st order tetrahedral
2nd order tetrahedral
1st order hexahedral
2nd order hexahedral
Table 1: The details of each mesh that was simulated within the validation project
Steel (linear elastic)
isotropic: \(E\) = 205 \(GPa\), \(\nu\) = 0.3 and reference temperature \(T_o\) = 293.15 \(K\)
Fixed x-translation of face ABCD and face A’B’C’D’
Elastic support on the faces ABCD and A’B’C’D’, with a total isotropic stiffness of \(K\) = 1000 \(N \over \ m\)
Fixed temperature of 303.15 \(K\) on all faces.
The analytical solution for the unit stress is given by the following equation:
