Pygmsh example. Merged surfaces. We are now ready to mesh the geometry after a call to occ.synchronize().. Quadrilateral meshing with gmsh. The most convenient quadrilateral mesh approach in gmsh is to use transfinite interpolation. An example of transfinite interpolation is the Coon's Patch.. For this approach to work, we need to assign the number of nodes along selected lines.
