How to create a fluid cavity surface for fluid cavity interaction in Abaqus

[Emre SENGUL]

thread799-384267

Hello,

I try to create a nucleus pulposus model and how can I define my geometric model as a fluid cavity? When I try to define a fluid cavity interaction, I couldn't see the volume surfaces of the nucleus in the set list. How can I create and put the fluid cavity set in the interaction set (including reference node)?

regards

It's not necessary to pick regions from list of predefined sets in Region Selection window. You can click "Select in Viewport" and then you will be able to pick regions directly in Viewport.
