It's more important to have proper element sizes, even if they are prism wedge and tet element shapes.
The outer geometry looks like a symmetric slice of a cup-shaped container. I expect the conical face of the cup is a wall, so you need to add inflation there. The bottom of the cup is a wall, so you need inflation on that face. What is at the top of the cup? What is the purpose of the different bodies at the bottom and top? Have you put the three bodies into a multibody part?
Please explain some of the other boundary conditions. You want smaller elements where you expect high gradients in solution quantities. Have you run a preliminary solution?
