Hi All, <br><br>Given an STL file, I would like to create a circular patch on the surface where the mesh density would be higher than the rest of the mesh (and uniform).<br>The result should like something like the attached picture, where the green circular patch is meant to represent an electrode on a cylindrical object (this is part of the EIDORS project).<br>
<br>In Netgen, we achieve that by intersecting a small cylinder (with high mesh density) with the main volume and then only keeping the surface at the intersection.<br>However, this seems to only work for programatically-defined geometries, and not stl files, hence I'm looking into gmsh.<br>
<br>I had a look at the stl remashing examples, but didn't see a way to define a patch on the surface. <br>I'll be grateful for any hints.<br><br>Best wishes, <br><br>Bartek<br>
