Dear Dr. Geuzaine I am Ph.D. student at Laval University. For my project I have to use the map which are prepared before by GIS. It means on the maps there are many Homogen polygon that I have to mesh (Triangle) for my modeling (Groundwater Modele). I`d like to know what is the best approch for doing this, and what is the advantage and disadvantage of each approch. Thanks a lot Javad Darehshiri
