DDPM-Polycube Core: A Denoising Task
DDPM-Polycube redefines hex mesh generation by treating the deformation from input geometry to polycube structures as a denoising task. It leverages a modified Denoising Diffusion Probabilistic Model (DDPM) to learn complex geometric transformations, generating polycube structures iteratively. This contrasts with traditional methods that rely on explicit templates, offering enhanced generalization for complex engineering designs.
Hex Mesh Generation: Parametric Mapping & Quality
The generated polycube structures serve as a parameter space for all-hex mesh generation. The process involves parametric mapping from the input triangular mesh to the polycube surface, followed by octree subdivision. Integrated mesh quality improvement techniques, such as pillowing, smoothing, and optimization, ensure high-quality hex meshes suitable for Isogeometric Analysis (IGA), reducing element count and avoiding locking issues.
Volumetric Spline Construction: IGA-Ready Models
Building upon the high-quality hex meshes, the DDPM-Polycube pipeline constructs volumetric splines, specifically TH-spline3D. These splines maintain C0 continuity around extraordinary points and C2 continuity in regular regions, crucial for accurate Isogeometric Analysis (IGA) simulations. The system supports local refinement and can export Bézier information for seamless integration with IGA solvers like ANSYS-DYNA.
Generalization & Efficiency: Beyond Training Data
The DDPM-Polycube model demonstrates remarkable generalization, creating polycube structures for geometries with genus levels beyond its training data (e.g., genus-0 to genus-2 and even deadhole geometries). While it may be slower than DL-Polycube methods for simple cases, it significantly outperforms traditional methods in handling complex, unseen topologies, making it a robust tool for advanced IGA applications.

Case Study: Generalizing to Genus-2 Topologies (The 'Eight' Model)
The DDPM-Polycube model demonstrates exceptional ability to generate polycube structures for geometries with complex topologies, even beyond its initial training scope. For instance, the 'Eight' model, a genus-2 geometry, was successfully processed.
Despite being trained on simple genus-0 and genus-1 primitives and only a single combination type, the algorithm effectively identified and deformed its parts into a topologically consistent polycube. This critical capability highlights DDPM-Polycube's strength in inferring and combining learned deformation characteristics, rather than being limited by predefined templates, making it highly valuable for diverse and previously unseen industrial designs.
