quadmesh 0.1.0

QuADMESH+: Quadrangular ADvanced Mesh generator. Python port of MATLAB QuADMESH library.

quadmesh

Tri-to-quad mesh generator. Port of MATLAB QuADMESH+. Build on chilmesh.

Pipeline

tri -> create_quad_domain -> tri2quad -> post_process -> quad

1. create_quad_domain — pick tris (whole mesh or polygon mask).
2. tri2quad — sweep layers outward, merge tri pairs into quads.
3. post_process — doublet collapse, quad-vert merge, boundary cleanup, smooth.

Install

pip install -e .
pytest          # 25+ tests

Use

from chilmesh import CHILmesh
from quadmesh import tri2quad, post_process, two_part_smoother

tri = CHILmesh.read_from_fort14("mesh.14")
quad = tri2quad(tri)
quad = post_process(quad, n_smooth_iter=50)

CLI

quadmesh mesh.14 -o out.14
quadmesh mesh.14 -o out.14 --no-remove-edges --n-smooth-iter 100
quadmesh mesh.14 -o out.14 --no-post-process

v0.2 new

• CleanupBoundaryQuads shift mode (can_remove_edges=False). Move corner inward. Before: no-op. Now: work.
• two_part_smoother. Interleave angle + FEM smooth. Port of MATLAB twoPartSmoother.m.
• 25+ tests.
