See grid_4() function in this tutorial +for an example. Note that the given result could also be achieved using the 3d +version of hyper_cube_with_cylindrical_hole(). The main usage is a 2d mesh +generated for example with gmsh, that is read in from a .msh file as described +above. This is the output from grid_4():
