Quadtree grid generation: Information handling, boundary fitting and CFD applications
The quadtree grid generation technique is reviewed and its programming is discussed. Three data storage methods are examined. The conversion of the quadtree grid to a triangular finite element mesh is also described, along with methods for fitting the mesh to smooth boundary contours. Results from viscous flow and standing wave simulations are used to illustrate mesh adaptivity about internal and boundary features.
