Pressure Vessel: Verification and Validation

"Verification and validation" can be thought of as a formal process for checking results. We previously performed some sanity checks on the deformed shape. A further basic check is how the results change on refining the mesh. The following video shows how to recalculate the results on a refined mesh. Note that it comes from a different project, but the procedure is the same. 

Mesh refinement results: 

Our results converged with a mesh of element size of 0.1 in. 

Comparison with thin and thick-walled theory from the pre-analysis:

Our FEA model confirms that the thick-walled approximation is more adequate for this geometry.
