Hi, I have a high-resolution STL surface (~100k triangles) and I want to create a 3D tetrahedral mesh of the interior for CFD simulations. The first step is to remesh the surface to a more reasonable resolution.
Now the thing is that I want to do second-order curved elements for the boundaries for better accuracy/performance of the CFD, which is quite expensive. Image of 2D version of what I want to do is linked here: http://imgur.com/a/h5834. This means that the extra side-nodes should be placed on the high-resolution geometry, not just as a linear interpolation of the corners. NetGen does this very well, but I would like to use gmsh instead since it doesn't crash as much. :o) Can this be accomplished in gmsh? I have played around with the surface remeshing features according to https://geuz.org/trac/gmsh/wiki/STLRemeshing (user/pass: geuz), but no luck so far. Maybe I'm missing something elementary.
