%K domain partitioning, mesh, quadrilateral.
%X 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.
