This tutorial demonstrates the usage of different refinement projectors. Refinement projectors are important if calculations are to be performed on spherical or cylindrical domains or if domains contain spherical or cylindrical parts.

ATTENTION: When applying a spherical projector to the whole geometry, one should make sure that the center of the projection aligns with a vertex or is located in a cutout. The same holds true for a cylinder. Here either the axis of the cylinder should pass through a set of edges or should also be located in a cutout.

Below you'll find the scripts sources. They are the same as in apps/tutorials/tut12_refinement_projectors.lua
