Parallel adaptive refinement for unsteady flow calculations on 3D unstructured grids
Journal Article

· International Journal for Numerical Methods in Fluids
A parallel adaptive refinement algorithm for three-dimensional unstructured grids is presented. The algorithm is based on an hierarchical h-refinement/derefinement scheme for tetrahedral elements.The algorithm has been fully parallelized for shared-memory platforms via a domain decomposition of the mesh at the algebraic level. The effectiveness of the procedure is demonstrated with applications which involve unsteady compressible fluid flow. A parallel speedup study of the algorithm also is included.
