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.

I tested it in the commericail version of ANSYS 2024R1 Autodyn. I couldn't reproduce the error as you observed. See attached picture below.

The same material can be filled into either Lagrange or Euler grid without showing any problems.

Are you able to get the latest release of ANSYS 2024R1 and try it again?
