Summary0003642: Sigma XX values for plateHole Case in UserGuide are not correct
DescriptionWith OpenFoam 8, I followed the steps mentioned in the user guide for the stress analysis of a plate with hole:
https://cfd.direct/openfoam/user-guide/v8-plateHole/#x6-390002.2

I didn't change anything, I just:
- copied the case into my $FOAM_RUN
- Generated the mesh with blockMesh
- Run the solver with solidDisplacementFoam

The maximum sigma xx stress obtained for the time step 100 is 2.5e8 Pa.
The image from the user guide shows a maximum value of 3e4 Pa (30 kPa)

I tried to come back to an earlier value of OpenFoam and recalculated with OpenFoam v5
Results come as in the user guide with the v5

Seems like something has changed in the v8
Either the Case need to be updated or there is a bug somewhere in the solidDisplacementFoam Solver

Steps To Reproduce- copy the case into my $FOAM_RUN
- Generated the mesh with blockMesh
- Run the solver with solidDisplacementFoam
TagsNo tags attached.
