How to Fill Internal Geometry with a Fluid

Please login with a confirmed email address before reporting spam

Hello, I am simulating a complex geometry in COMSOL that consists of various shapes (e.g., cones, cylinders), each with different radius. I want to fill all the internal hollows and gaps inside this geometry with a fluid. However, I do not want to create a separate cylinder or other simple geometry for filling, as the internal shape is quite complex and non-uniform.

Could someone please advise on the best method to automatically fill the entire internal space of such a complex geometry with a material? Any suggestions would be greatly appreciated!

Thank you!
