Could you build this?
No Developing a hex-dominant Cartesian cut-cell CFD mesher that outputs valid OpenFOAM polyMesh files demands advanced computational geometry and numerical simulation expertise.
What it would actually take: The project requires implementing 3D computational geometry algorithms: octree spatial partitioning, ray-triangle intersection tests, arbitrary polyhedron clipping against CAD geometry (STL/STEP), and mesh quality optimization (aspect ratio, non-orthogonality, skewness). It also requires generating OpenFOAM polyMesh topological structures (points, faces, owner, neighbour, boundary files) in C++. This necessitates specialized knowledge in finite volume methods, computational geometry, and CFD pre-processing.
