Future of QuadTri code
The QuadTri code, contributed by Trevor Strickler, allowed to generate hybrid 3D structured (Transfinite or Extruded) and unstructured meshes in a semi-automatic way (by modifying the structured part), before an automatic algorithm (which modifies the unstructured part) was added in Gmsh 4.0.5.
QuadTri is explained here: https://gitlab.onelab.info/gmsh/gmsh/blob/master/benchmarks/extrude_quadtri/READMEQUADTRI.txt
This issue is created to collect feedback about the future of the QuadTri code:
- is it still actively used?
- does it address cases that the new automatic algorithm does not?
If QuadTri is not actively used anymore it could be removed in a future release.
