Then I would try to just do a Delaunay triangulation of your points. gmsh has a plugin for that. But I have never done that kind of thing, please ask on the gmsh list for further assistance. I forward this mail also to the list.

I need a 2d mesh for the domain to simulate the tsunami. Thanks in advance, Rachid Van: Zenker, Dr. Matthias [mailto:[email protected]] Verzonden: dinsdag 11 februari 2014 11:02 Aan: Rachid Abraimi CC: [email protected]<mailto:[email protected]> Onderwerp: AW: [Gmsh] Important question for my Thesis Hi Rachid, you could try to do a Delaunay triangulation of your points to get a surface representing the ground. You might have to project your points onto a plane since normally Delaunay triangulation works only in 2d AFAIK. Once you have the ground, you can define additional points at the edges of the volume you want to consider, define lines and surfaces and finally the volume. Then you can do a mesh3D. For details, consult the gmsh documentation and ask the gmsh mailing list. HTH, Matthias Von: Rachid Abraimi [mailto:[email protected]] Gesendet: Dienstag, 11.

The topography data is a text file containing the depth for each point in the domain. Is it possible to import this data and give gmsh the command to perform a depth-depended triangle size?
