Bases: object

Controls for the vtkSurfaceNets3D surface extraction stage.

Controls for building the ConformalSurfaceComplex.

Bases: object

Tolerances for the pre-tet surface validation gate.

class upxo.meshing.confMesh3d.config.SurfaceRemeshConfig(enabled: bool = False, algorithm: int = 6, mesh_size_factor: float = 1.0, optimize_iterations: int = 5, verbose_gmsh: bool = False)

Bases: object

Controls for the optional Gmsh surface quality-optimization stage.

v1 scope: relax/optimize the existing SurfaceNets3D triangulation in place (Laplacian-style vertex relaxation of interior points only). Boundary vertices (shared by >=2 patches – triple lines / RVE edges) are never moved, so conformality across patches is preserved by construction. Does not re-parametrize or regenerate patches from scratch (that is a harder, deferred v2).
