Hello,

To overcome highly dostorted elements error, you can ensure good mesh quality by using elements that are less susceptible to distortion, using a mesh with appropriately shaped elements, or applying loads in smaller increments. Additionally, you need to ensure that the model is set up correctly, which includes using complete test data and a stable material model. In some cases, changes to the design geometry may be necessary to limit localized excessive element distortion.
