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 Harry,

Are you using the material from the Ansys database or do you have any test data for the material you want to use?  Also, what type of Analysis are you doing? As per the error message, it looks like you need some material property data which is not defined in your material definition.

Thanks,

Akshay Maniyar
