cubit-mesh-export 0.1.0

High-order curved mesh export from Coreform Cubit to NGSolve/Netgen

cubit-mesh-export

High-order curved mesh export from Coreform Cubit to NGSolve/Netgen.

Features

• Arbitrary-order curving (order 1-5) via ACIS geometry projection
• Label preservation: material (block), boundary (sideset), edge (BBND)
• Companion JSON: CAD reference values for Volume/Area/Length consistency checking
• Standalone checker: verify mesh quality without Cubit (check-vol CLI)

Install

pip install cubit-mesh-export

Usage

Export (requires Cubit)

import netgen       # must import before cubit
import ngsolve
import cubit

cubit.init(['cubit', '-nojournal', '-batch'])
cubit.cmd('open "model.cub5"')

from cubit_mesh_export import extract_curved_mesh
ng_mesh = extract_curved_mesh(cubit, order=3)
ng_mesh.Save("model.vol")

Check (does NOT require Cubit)

check-vol model.vol

from cubit_mesh_export.check import check_consistency
results = check_consistency("model.vol")
