Hi,<br><br>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.<br>
<br>Any can help me !!!<br><br>Thanks,<br><br>Sebastian Giusti<br>National Technological University - Faculty of Cordoba<br>Civil Engineering Department<br>Cordoba - Argentina<br>
