This algorithm can be used only together with Quadrangle (Mapping) This algorithm can be used together with Quadrangle (Mapping) and Netgen 2D
algorithm. It allows to build quadrangular meshes even if the number algorithms.
It allows Netgen 2D to build quadrangular meshes at any conditions.
It allows Quadrangle (Mapping) to build quadrangular meshes even if the number
of nodes at the opposite edges of a meshed face is not equal, of nodes at the opposite edges of a meshed face is not equal,
otherwise this mesh will contain some triangular elements. otherwise this mesh will contain some triangular elements.
