<div>Hello,</div><div><br></div><div>I am trying to create a mesh for a cylinder that sticks in another solid. </div><div>For this purpose, I generated 3 non-closed meshes using the boolean operations of Rhino 3D: one for the surface of the part of the cylinder that is inside of the solid, one for the part sticking out and one for the surface of the solid (with a hole, but without the mesh described first). I merged all 3 (STL) files in Gmsh, reclassified the resulting mesh and tried to remesh as described in tutorial 13 (I defined surface loops and volumes for both the cylinder and the solid with the "drill-hole").</div>
<div><br></div><div>However, after 2D remeshing (and ignoring several "Vertex ... not found" errors) there are small gaps and overlaps around the hole. The meshes for the upper and lower part of the cylinder form a nicely closed mesh, though. Any other combination of meshes leads to gaps and overlaps.</div>
<div>2D remeshing and 3D meshing worked for a cylinder sticking in a cube, but a "curved" surface seems to cause problems. I've already tried a lot of combinations of meshing algorithms, geometry (healing and tolerance) settings, reclassify options, remesh parameters, surface normal orientations etc. </div>
<div><br></div><div>Please see the attached files for an example. Any suggestion on how to solve or work around this problem? </div><div><br></div><div>Thanks in advance!</div><div>Kind regards,</div><div>Markus</div>
