Partitioning and Dynamic Load Balancing of Adaptive Hybrid Grids for Large-Scale Turbulent Flow Simulations

A new partitioning method for complex 3-D hy-brid prismatic/tetrahedral meshes is presented, The method uses an orthogonal recursive bisection ap-proach on a special octree corresponding to the hybrid grid. The octree is generated automatically and han-dles any type of 3-D geometry and domain connectiv-ity. It is employed for partitioning of static, as well as dynamic adaptive meshes. The method yields similar quality partitions for very different geometries, such as a sphere and an aircraft configuration. The strat-egy for load balancing is applied to octants which leads to an efSicient parallel algorithm. Results include par-titioning a hybrid grid around an aircraft configura-tion and octree-based load balancing for a dynamically adapted mesh. The method is applied to large-scale turbulent flow simulations around aircraft configura-tions.
