We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi, 

I am not sure if you have an ALE Domain set in your LSDYNA WB model. 

This ALE Domain will set the surrounding mesh so that the fill material can flow in it. 

I guess this should fix the issue. MAT_JOHNSON_COOK and *EOS_GRUNEISEN are now directly supported in the newer versions. 

Cheers, RamÂ
