How to define a meshed 3D surface from a set of points
Dear users,
Sorry in advance if this question has already been asked, I found nothing to help. Using Gmsh, I want to build a mesh of a 3D box whose top surface is topography. This topography is defined by a DEM i.e. a set of points (x,y,z) where z is the elevation and (x,y) are known on a cartesian grid. How to include this set of points to generate a surface, meshed in triangles, to finally have a 3D mesh with tetraedra ?
Thank you in advance for help, Nathalie Glinsky
