Unstructured Adaptive Meshing

چکیده
We explore the current capabilities of the recently released Myricom X2OOO witch, using MPICH over the GM communication layer; for message passing on a 2-way SMP Pentium III Beawulf-Class cluster: Performance measurements on the network indicate that data transfer rates of appmximatety 190 Mbyteds for ping-pong tests, and 24OMbyteds forfill-duplex exchange tests, can be achieved for messages as large as 32 Mbytes. The perf onruutce varies depending on how processors communicate; either within an SMP node or across nodes. Results with the network for parallel unstructured adaptive refinement of 3 0 tetrahedral meshes show noticeable perfonnance improvement when compared to lOOBaseT Ethernet. Furthemre, when compared to traditional systems such as the SGI Origin 2000, the combination of this fast network with high pet$ormunce SMP processors demonstrate that Beowulf-Clusters compare favombty with such system-even when communication intensive applications are used.

Building Effective Parallel Unstructured Adaptive Simulations by In-memory Integration of Existing Software Components
There is an increasing demand for mesh-based PDE simulations to provide reliable solutions for complex problems. A key step in ensuring simulation reliability is the application of unstructured adaptive meshing driven by error estimation procedures. Typically, interfacing of unstructured adaptive procedures with existing analysis components is done through files. File I/O is currently the criti...

متن کاملAdaptive Mesh Generation for Tcad with Guaranteed Error Bounds
An adaptive three-dimensional mesh generation strategy is presented. In contrast to other work which is based on simple meshing techniques, we use advanced unstructured meshing techniques, driven by error estimators, to realize automatic adaptation and guarantee quality. The mesh optimization strategy is based on a classification scheme with a fuzzy indexing for the degree of degeneration of th...
متن کاملMultigrid Solution Strategies for Adaptive Meshing Problems
This paper discusses the issues which arise when combining multigrid strategies with adaptive meshing techniques for solving steady-state problems on unstructured meshes. A basic strategy is described, and demonstrated by solving several inviscid and viscous ow cases. Potential ine ciencies in this basic strategy are exposed, and various alternate approaches are discussed, some of which are dem...

Over planar domains and on curved surfaces, triangular and quadrilat...
متن کاملAdaptive 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...
