                         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.",
