FASTWO-A2-D (Five Algebraic-Step TWO-dimensional) Interactive Algebraic Grid Generator

摘要

This paper presents a very simple and effective computational procedure, FASTWO, for generating patched composite finite difference grids in 2-D for any geometry. Major components of the interactive graphics based method that is closely akin to and borrows many tools from transfinite interpolation are highlighted. Several grids produced by FASTWO are shown to illustrate its powerful capability. Comments about extending the methodology to 3-D are also given. (Reprints)
