Volume mesh Delaunary issue
 

Hello.


I want to generate a Delaunary volume mesh. the geometry consists two two ball, one inside the other. I want to just mesh the volume between the two inner, outer ball. But ICEM ignore the inner ball and generate a mesh for the hole geometry. Since ICEM don't need boolean, what should I do to exclude the volume in the inner ball a mesh only the volume between two balls?
thanks.

Define material points and only make visible the volume material point where you want to have mesh.
