Mesh and Element Types: The meshes used for cases A and C were created in SimScale with the standard algorithm. The mesh used for cases B and D is a hexahedral mesh that was created locally.

Find below the mesh used for cases A and C. It’s a standard mesh with second order tetrahedral cells.

Cases B and D are run on a 2nd order hexahedral mesh, which is shown below:

Result Comparison
The results obtained from SimScale for the Cauchy stress \(\sigma_{yy}\) along the FC line are compared to the values of reference from [SSNP123]\(^1\). These values of reference were extracted with WebPlotDigitizer. Figure 5 shows the results for cases A and B, where element technology is set to standard:

Similarly, for cases C and D, where reduced integration was used:
Figure 6: Comparison of cases C and D with the reference values from [SSNP123]¹
In both Figures 5 and 6, SimScale’s results show good agreement with the reference values.
