报告题目: Variational Method for Mesh Generation

报告摘要:Quad and Hex mesh have wide applications, and automatically generating high quality hex/quad mesh got a lot of attention in these years.  Most of the challenges relate to the discrete properties, such as integer number of intervals, sparsely distributed singularities, rotational symmetric smoothness etc.  This talk will mainly about our recent progress of turning the formulations from discrete into continuous, which leads to variational way for mesh generation.  Besides, we will also talk about mesh quality measurement and the impact of discretization.

报告题目:Automatic and Parallel Mesh Generation: Recent Advances

报告摘要:Mesh generation is recognized as the main performance bottleneck in simulations involving complicated geometric definitions and/or complex physical behaviors. Automatic generation of high-quality meshes remains a challenging issue. Besides, lots of simulations are now demanding meshes consisting in hundreds of millions of elements or more. It could be very difficult and inefficient to create such big meshes by sequential algorithms due to the bottlenecks of memory usage and computing time. In this talk, Dr. Chen will present three technologies developed by his research group recently, as part of his efforts to develop a completely automatic and parallel meshing system for real-world simulations. These technologies are: (1) Automatic creation of a feature-aware and gradient-limited sizing function; (2) Automatic generation of high-quality boundary layer elements using vector fields computed by the boundary element method; (3) Distributed and/or multi-threaded parallel mesh generation and mesh quality improvement. Mathematic models behind these technologies will be investigated in this talk, plus important algorithmic details. Meshing examples are selected to show that the developed technologies are applicable to configurations of a complication level experienced in industry.
