Hi all,

I have upgraded Hypermesh/Hyperworks to 2021.2 version but I couldn't find new material models such as mat law 112 in Hypermesh and Hyperworks. What could be the possible reason of that ? You can see my system information down below. By the way Radioss user interface is selected in hypermesh.

Thanks in advance,

Best regards,

Ufuk

    What material should be Law 112? What are you looking for?

     

    Are you sure that you're talking about Radioss? Or are you talking about Dyna?

    I'm talking about Radioss. I'll use /MAT/LAW112 for corrugated paperboard. But I couldn't see that material card in material selection.

    now i found it in Radioss documentation. Sorry abouth that.

     

    I believe this is not supported yet by HM interface. Probably it will come in next versions.

    The workaround would be to create it manually, in a separate text file, and then add it as an include file into your model.

     

    I believe you can create a dummy material in your model, with the ID of your manuallly created material, and assign this to your part. You can leave it as 'undefined'.

    then create and include pointing to your material.

    Hi

     

    Yes , /MAT/LAW112 was released within the Radioss version 2021.2

    But it happens that the preprocessor may be not in sync with the solver keywords.

    You may need to edit the deck in separated text editor, 

    or if you need you can create the file separated and refer as #include in the master file deck

     

    I hope this is helpful

    Regards
