It's called Element Orientation (inserted under the Geometry branch in the tree:Note in the image above the the element coordinate systems have their blue (z) axes pointing radially. There are four 90 degree sectors in the geometry. The four faces that I used as a "surface guide" upon which the resulting z direction is based were the outer four cylindrical surfaces extending a full 360 degrees. The four edges I used as an "edge guide" upon which the resulting x direction is based where four cylindrical edges extending a full 360 degrees. Hope this helps. I did this at 2022R2. In earlier versions of WB you might have to resort to an APDL command object - tedious but doable.
