Name: QuadMesher

External dependencies: Mesquite (optional)

Input: 2D ModelEnt's, meshed with triangles

Output: Mesh vertices, quadrilaterals, committed to ModelEnt

Interface(s) used: iGeom, MOAB

Setup:

Looks on the ModelEnt for an assigned tri mesher, and if none is found, assigns one from the default list of tri meshing algorithms registered with MeshKit. No check is made on the number of bounding intervals being even; if this number is odd, one triangle will remain after this algorithm is finished.

Notes:

This class implements quadrilateral mesh generation, based on triangle recombination. Triangles can be generated with any algorithm. Irregular nodes are removed using Bunin's algorithm.
