Mapped mesh and toroidal extrusion

How can you map a toroidal shape like a fillet?

For exercise, I would try to mesh a simple sample like those in the pic with "mapped mesh" and "prismatic elements" controls.

Thanks

It is all about smooth transitions that do not distort elements from rectangles too much.  This is easier if every 90 degrees is split into 3 parts of 30 degrees, both along the fillet and around the revolve. Note, the white lines were made mostly by revolved quilts made into volume regions.  Also note the the inner edges of elements do not have curvature.  As shown, the revolve is split into every 22.5 degrees (only meshed one of them).  And of course when using volume regions remember to set the default interface to bonded.

Hi, however I had looked for the manner to use "mapped mesh" and "prismatic elements" together.
