Prof. Dr. David Bommes – Hexahedral Mesh Generation with Integer-Grid Maps

Computer Graphics Group, Institute of Computer Science, Universität Bern, Switzerland


Automatically generating hexahedral meshes is a notoriously challenging task, specifically if alignment to freeform surfaces combined with high mesh regularity and low distorted elements is required. Novel algorithms based on global optimization rely on the construction of integer-grid maps, which pull back a Cartesian grid of integer isolines from a 3D domain onto a structure-aligned hexahedral mesh. Such global optimization algorithms do not suffer from limitations known from local advancing front methods, as for instance, a high rate of irregularity, and enable meshes comparable to manually designed ones by finding a good compromise between regularity and element distortion. The key to efficiently finding high-quality solutions are frame fields that are employed to optimize the orientation and sizing of mesh elements globally. In my talk, I will give an overview of the state of the art and discuss the strengths and weaknesses of available algorithms, including open challenges for hexahedral mesh generation.
