upxo.meshing.gbconformant.d3v2p1.discrete_topology module

d3v2p0.discrete_topology with the .msh text written by a few bulk formatting calls; the file content is byte-identical to d3v2p0’s.

upxo.meshing.gbconformant.d3v2p1.discrete_topology.add_chart_topology(gmsh, points, triangles, groups)

Import charts with explicit shared curves, retaining source element tags.

A curve joins consecutive edges having the same incident chart set. Curves end at branches; closed chains are split in two to give ordinary endpoints. This avoids Gmsh’s expensive rediscovery of thousands of small chart seams.
