The most important to the success of finite element analysis as the accuracy of the finite elements. The patch-tests is a simple method to check the behaviour and the quality of the finite elements.
The patch-tests should be performed when first using any finite element program.
The patch-tests both ensures that the theory for the finite element formulation has been correctly implemented and that the analysis system is also correct.
The patch-tests also ensures that both regular and irregular elements garantee same behavior.
The following manual contains the patch-tests of AxisVM finite elements.
