Geometrically based, automatic generator for irregular triangular networks
R. Falconer Henry, Roy A. Walters · Communications in Numerical Methods in Engineering · 1993
Abstract The network generation method described herein produces two‐dimensional irregular triangular grids in which element area is proportional to some scalar density function defined over the domain. This density function can reflect arbitrarily chosen properties of the geometry or flow. After the initial generation, various adjustment utilities and an interactive (graphic‐based) editor ensures that the resultant triangular elements are well shaped. Some of these utilities can be used with adaptive refinement schemes.
