We want to apply seven levels of refinement everywhere on the sphere surface, so we set the same values for the minimum and maximum levels of refinement. These are controlled in the refinementSurfaces section, which should look like this. refinementSurfaces {sphere {// Surface-wise min and max refinement level level (7 7);}}
