Abstract
The network generation method described herein produces two-dimensiona l irregular triangular grids in which element area is proportional to some scalar density function defined over the domain. This density fun ction can reflect arbitrarily chosen properties of the geometry or flo w. After the initial generation, various adjustment utilities and an i nteractive (graphic-based) editor ensures that the resultant triangula r elements are well shaped. Some of these utilities can be used with a daptive refinement schemes.
