Mesh Interface Resolution and Ghost Exchange in a Parallel Mesh Representation
Parallel and Distributed Processing Symposium Workshops & PhD Forum（2012）
摘要
Algorithms are described for the resolution of shared vertices and higher-dimensional interfaces on domain-decomposed parallel mesh, and for ghost exchange between neighboring processors. Performance data is given for large (up to 64M tet and 32M hex element) meshes on up to 16k processors. Shared interface resolution for structured mesh is also described. Small modifications are required to enable the algorithm to match vertices based on geometric location, useful for joining multi-piece meshes, this capability is also demonstrated.
