abstract = "One of the main challenges in quadrilateral mesh generation is to
ensure the alignment of the elements with respect to domain
constraints. Unaligned meshes yield numerical problems in
simulations that use these meshes as a domain discretization.
There is no alignment metric for evaluating the quality of
quadrilateral meshes. A directionality field represents the
diffusion of the constraints orientation to the interior of the
domain. Kowalski et al. use a directionality field for domain
partitioning into quadrilateral regions. In this work, we
reproduce their partitioning method and adapt it to reduce the
final number of partitions. We also propose a new metric to
evaluate the quality of a quadrilateral mesh with respect to the
alignment with domain constraints.",
