Hi, I am working with jpg image into gmsh. At this instant I need detect (within gmsh) inside the image different objects or regions to automatically create the corresponding "phisycal lines and surfaces". After meshing the image, I need, from the output mesh file, the nodes and elements that belong to each line and surface, respectively.
Any can help me !!! Thanks, Sebastian Giusti National Technological University - Faculty of Cordoba Civil Engineering Department Cordoba - Argentina
