When creating an FE mesh, a message appears saying that distorted elements have been detected. What should I do?

Answer

The display of the FE mesh quality can help you with the calculation of planar structural components. When generating the mesh, the created FE elements are subjected to an internal check according to specific criteria. The result can be displayed graphically. Three quality levels are displayed in green, yellow or red.

The values of the checked criteria can be customized. Thus, you can adjust them to your individual requirements.

In this way, the FE mesh quality check allows for an evaluation of discretization. For example, it is possible to localize areas that require FE mesh refinement. However, it cannot replace the engineering control of the FE mesh by the user.
