The poloidal shape is now represented with 5 cells just like the +circle. Furthermore, the function GridGenerator::torus() has gained an +optional argument to control the number of cell layers in the toroidal +direction. The default manifold set to the torus has also been improved: Now, +the TorusManifold is applied on the surface, a CylindricalManifold to the +middle cells in toroidal coordinates, and a TransfiniteInterpolationManifold +on the cells between the surface and the inner ring. This leads to an +excellent mesh quality for all supported scenarios. +
