Repair

Tools for fixing common mesh problems. Individual repair operations are available as standalone functions, and repair_mesh() chains them into a single pipeline.

Available operations:

• Merge duplicate points: collapse vertices within a tolerance

• Remove duplicate cells: eliminate cells with identical vertex sets

• Remove degenerate cells: remove cells with zero area/volume

• Remove unused/isolated points: clean up unreferenced vertices

• Fix orientation: ensure consistent face winding

• Fill holes: close open boundaries

The all-in-one clean_mesh() function (also accessible as mesh.clean()) applies the most common subset of these operations. For full control, use repair_mesh() or call individual functions.

from physicsnemo.mesh.repair import repair_mesh, clean_mesh

# Quick cleanup
clean = mesh.clean()

# Full repair pipeline
repaired = repair_mesh(mesh)

# Individual operations
from physicsnemo.mesh.repair import (
    merge_duplicate_points,
    remove_degenerate_cells,
    fix_orientation,
    fill_holes,
)
mesh = merge_duplicate_points(mesh)
mesh = remove_degenerate_cells(mesh)
mesh = fix_orientation(mesh)
mesh = fill_holes(mesh)
