报告摘要:
In the CAE domain, hexahedral meshing is widely regarded as the “Holy Grail,” due to its superior numerical accuracy and difficulty relative to tetrahedral meshing. It remains the core bottleneck for Isogeometric Analysis. In this talk, I will present two theoretical contributions of my Ph.D. research, which target long-standing open problems in grid-based hexahedral meshing. The first work aims to reduce the number of background hexahedral cells under a given adaptive octree, so that future algorithms can scale up to handle more complex input geometries within limited memory budgets. The second work introduces the Marching Cubes algorithm into the meshing pipeline. It ensures that, prior to the nonlinear optimization in the final trimming step, the interior–exterior interface of the hexahedral mesh already converges to the input geometry at a faster rate, while also establishing a theoretical lower bound on mesh quality. This is the first hexahedral meshing algorithm that provides both a second-order convergence rate in Hausdorff distance and a guaranteed positive minimum Jacobian determinant.
