Hello,

This is my first time using the ACP modeling tool for composites, and I had went through a few online tutorials to familiarize myself with the software. When I attempt to run an explicit dynamic simulation with the composite solid model, it gives me this error:

"Retrieving Parts Data .....Error! Material with invalid equation of state assigned to surface body."

I have searched online, but can find no information about the issue, so anything would be helpful.

Thanks
