FEA Practical Illustration of Mesh-Quality-Results Differences between Structured Mesh and Unstructured Mesh

Parallel Unstructured Mesh Partitioning

Scalable Unstructured Mesh Decomposition

As the e ciency of parallel software increases it is becoming common to measure near linear speedup for many applications. For a problem size N on P processors then with software running at O(N=P ) the performance restrictions due to le i/o systems and mesh decomposition running at O(N) become increasingly apparent especially for large P . For distributed memory parallel systems an additional l...

76 Parallel Unstructured Mesh

The use of unstructured mesh codes on parallel machines can be one of the most e cient ways to solve large Computational Fluid Dynamics (CFD) and Computational Mechanics (CM) problems. Completely general geometries and complex behaviour can readily be modelled and, in principle, the inherent sparsity of many such problems can be exploited to obtain excellent parallel e ciencies. An important co...

Adaptive and Unstructured Mesh Cleaving

We propose a new strategy for boundary conforming meshing that decouples the problem of building tetrahedra of proper size and shape from the problem of conforming to complex, non-manifold boundaries. This approach is motivated by the observation that while several methods exist for adaptive tetrahedral meshing, they typically have difficulty at geometric boundaries. The proposed strategy avoid...
