Cubit Paving Algorithm

This animation demonstrates the default paving algorithm in Cubit, which uses a cleanup step to remove triangle- and bowtie-shaped quadrilaterals. This cleanup option, while default, can be selected with the following command: "paver cleanup on" Paving (Blacker; White) allows the meshing of an arbitrary three-dimensional surface with quadrilateral elements. Paving supports interior holes, arbitrary boundaries, hard lines, and zero-width cracks. It also allows for easy transitions between dissimilar sizes of elements and element size variations based on sizing functions.
