To Perform the Test:
The cantilever_thin_square_plate_test2.CATAnalysis document presents a complete analysis of the test 2, computed with an irregular mesh formed of parabolic quadrangle elements (QD8).
To compute the three other tests, with other nodes of distribution, proceed as follow:
Open the CATAnalysis document.
In the Advanced Meshing Tools workbench, change the mesh specifications as indicated above.
Compute the case in the Generative Structural Analysis workbench.
