Hello. I am trying to create a model in which there is a cylinder containing two ellipsoids, which are contained within each other, one being larger than the other. The larger ellipsoid is s1 and the smaller ellipsoid is s2. I am trying to apply multiphysics to each but am running into an issue. For instance, when I try to assign a porosity to s1, it automatically highlights what is both s1 and s2. How do I get around this? I just want to be able to target s1 or s2, not both at the same time, as they serve different functions. Or, when I try to apply some sort of physics to the cylinder, it selects both the cylinder and s1, but not s2. I want the three geometry components of my file to be distinct. I feel like this is a simple geometry issue that I am not understanding.
