I am working on beam dumps at CERN and are trying to do a submodel. Does anyone have expertise in this? I would like to discuss a few points.

Hello,

If you have a valid LS-DYNA license, you can go on the Ansys customer portal and find the following knowledge resource on submodeling:

There is a presentation by Ozen (Ansys  channel partner) here:

And a paper on dynalook.com here:

You will find more information here:

Also, have a look at the following keywords in the LS-DYNA user manual Volume I:

*INTERFACE_COMPONENT_SEGMENT
