Hi Nitin,

 You can convert the Dyna model to RADIOSS using HyperCrash.

 Make sure you are using the latest HyperCrash 17.2 for the best translation. Start HyperCrash and pick the RADIOSS user profile.  After HyperCrash starts, go to File>>Import>>Ls Dyna, and select your Dyna model.  During import HyperCrash will convert the Ls Dyna model to RADIOSS model.

Please try with this.

Hi Nitin,

Please try in 2017.2, and I hope it should work.

In case if it still remains unsupported, you may have to create or update the same in RADIOSS.

Int he installation directory we have a file which gives the complete list of cards which are supported and unsupported for Dyna to RADIOSS.

I'm attaching the same for your reference. Please open the same in Textpad.

Hi Nitin,

You can model foam material with /MAT/LAW38 in RADIOSS, which is Visco-Elastic Foam Tabulated Material.

For MAT_DAMPER_VISCOUS you can use /PROP/TYPE13 , Beam Type Spring Property Set .
