Fill a hollow body for CFD

Hello,

I have the attached geometry. What would be the best way to fill such a body to create a fluid domain for CFD?

Thanks

Create another volume e.g. a cube in such a way, that it overlaps with nearly all of the body you have, except for the very endings of the tube. Now if you use a boolean operation (subtract the volumes from one-another) you will reveice an inner body (which is what you are looking for) and the outer body which you can delete.

This will give you a large part of the whole thing, but not everything. From there I would go and add the missing parts manually if possible.
