Modelling a protective foam around a skull

[hasnun]

Dear all,

I have an orphan mesh of a human skull in Abaqus. What I would like to do is to create a foam and wrap it around the skull (around the forehead area). So how do I go about doing this in Abaqus? The skull has irregular geometry. Your help is truly appreciated. Thanks.

In the Mesh module (can't recall if it is under Parts or the Assembly), edit the mesh to create an outer "shell". Read about it in the CAE User's Guide.

Hi IceBreakerSours, thank for your reply. I know about create the shell and solid from the mesh. I am interested in solid elements. But the problem is, if I would like to vary the thickness of the foam, would it be problematic? What if I wanted to play around with different designs as well, i.e. honeycomb foam. Would I be able to do this with that technique?

I always suggest creating complex geometries in your CAD program. A variable offset surface or offset honeycomb may even require a powerful CAD package.

I hope this helps.

Also, I noticed that you posted in the biomechanics forum. Generally this is frowned upon. I personally don't care but do like to see cross-reference links.

OK thanks. I'll try to figure out how to do this in CAD.

Sorry for the double posts.
