Hello everyone! I’m working on my Master Thesis and there’s something really stupid I’m not getting out of.<\/p>\n
I’m looking for a way to get in one shot (or almost!) the nodes of the mesh belonging to the outer perimeter.<\/p>\n
For example, having the area in the figure, I would need the coordinates x and y of the nodes belonging to the perimeter.<\/p>\n
Is there a command or a solution that does? In addition, I will then have to work with geometries that will have internal holes and that is why I wonder if there is a strategy that automatically selects the external nodes.<\/p>\n
