Aluminum foam using /MAT/LAW115

[avocadofruit]

Hi all, I'm trying to simulate a blast impact of aluminum foam using the material /MAT/LAW115 (DESHFLECK). It gives me the warning: Unsupported option /MAT/LAW115 in format < 2021.

Any ideas to resolve this?

Hi @avocadofruit ,
If your input format is posterior to 2021, this is likely a bug. In that case, I recommend sharing an input file.
However, if your format is anterior to 2021, you’ll need to update your input file by updating the Invers parameter in the /BEGIN option. You can find more details in the official documentation here: Radioss Manual - /BEGIN (Starter).

Hi, I managed to resolve it by changing Invers to 2024. Thanks a lot!
