Hello.
I'm trying to create a 3D ellipsoid surface(structured) with prism layers in a rectangular volume of fluid(Cartesian grids).
My approach was,
1. Create half of the volume of fluid to later apply symmetric plane.
2. Sketch half of an elliplse and the prism layer on the xyplane, and then revolve it around the ellipse's major axis.
3. Create a 'intermediate' rectangular block section that will connect the ellipse+prism to the outer Cartesian grid.
4. Create a Cartesian grid for the rectangular volume of fluid.
Would this be a common approach to this?


I have attached the some jpeg files of my current state(pw file is too large).
I got stuck at making the 'intermediate rectangular block', because I keep failing at the assembly of block.

Can someone show me how to get through this, or if I should take another approach?

Thanks a million.
