The URL of this survey http://www.andrew.cmu.edu/user/sowen/softsurv.html Some main points of this survey: As part of a survey of unstructured mesh generation technology, an informal survey was conducted during September 1998 of current mesh and grid generation software. Over 100 surveys were mailed to software vendors, research labs and educational institutions. This list is definitely not all-inclusive, but I believe is fairly representative of what is currently available, as well as what is state-of-the-art. Only those responding to the survey are included here. While the emphasis of the survey is unstructured codes, there is also a considerable number of structured codes included. The codes range from simple research codes that are used only by a few people, to commercial products incorporated into sophisticated analysis packages. Please send any corrections or additions to this list to Steve Owen at sjowen@sandia.gov or sowen@adelphia Another catalog of mesh generation software is available from CEWES, which also includes independant review information. I should also mention Robert Schneider's list of mesh generation software, which provided www information for most of the software in this survey.
