This paper follows a previous one that was dealing with high-quality surface remeshing using harmonic maps. . In it has been demonstrated that harmonic parametrizations can be used as input for surface meshers to produce high-quality triangulations. However, two important limitations were pointed out, namely surfaces with high genus and or of large aspect ratio. This paper addresses those two issues. We first develop a multiscale version of the harmonic parametrization and then combine it with a multilevel partitioning algorithm to come up with an automatic remeshing algorithm that overcomes the above-mentioned limitations of harmonic maps. The overall procedure is implemented in the open-source mesh generator Gmsh
