Since spheres, hemispheroids, ellipsoids, and related geometries are very common in a great variety of problems, some techniques have been developed to mesh this class of geometries with structured grid systems. Just as a butterfly grid can be used to grid a circular face, here we will demonstrate how this approach is used to create a 3D butterfly grid for meshing a hemisphere.
