I am doing a 2D internal flow simulation. I want the enclosing solid domains to be visible in the post processing. For example, I need the wall thickness of a pipe to be visible, not only its inner boundary.

If I suppress the solid domains and mesh only the fluid ones, all I see in CFD Post are the fluid domains and their boundaries.

If I mesh both the solid and fluid domains, I see the solid domains grayed out in CFD Post. Great, but isn't there a way to avoid the unnecessary meshing of the solid domains?

How can we display solid domains in post-processing without actually meshing them?

Any ideas?
