We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi igandiko,

’in a mess’ means the elements have a large deformation and overlap.

I find the error is result from the order of solid elements. Elements in above screenshots are second order. I change the elements into first order, the elements in d3rms file are normal, as below screenshot shows. However, result of first order is less accurate than second order.
