SIMMETRIX INC HAVE ANNOUNCED THE RELEASE OF PARALLEL MESHSIM
06 January 2007 - NAFEMS
| Parallel MeshSim provides a breakthrough technology for meshing of very large scale simulation problems based on a unique approach to meshing parallelization. Parallel MeshSim does not require the model representation to be reduced to a facet-based representation with a loss of data, but rather works directly with the GeomSim modules providing parallel mesh generation directly on geometry defined by the major geometry kernels (ACIS, Granite, Parasolid). Facet-based representations of geometry are also supported but not required. |
Parallel MeshSim provides a breakthrough technology for meshing of very large scale simulation problems based on a unique approach to meshing parallelization. Parallel MeshSim does not require the model representation to be reduced to a facet-based representation with a loss of data, but rather works directly with the GeomSim modules providing parallel mesh generation directly on geometry defined by the major geometry kernels (ACIS, Granite, Parasolid). Facet-based representations of geometry are also supported but not required. The same API used by MeshSim in serial is used in parallel and the majority of MeshSim’s features are supported in parallel. Both surface and volume meshing may be done in parallel and all aspects of load balancing are automatically managed by the software. The resulting mesh is partitioned across processors in a manner compatible with our Parallel MeshSim Adapt product, enabling parallel, adaptive analyses.
This unique approach is well suited to large complex far field simulations such as acoustics, CFD, and electro-magnetics that require a mesh of the inverse space or surrounding volume. The mesh parallelization is independent of CAD assembly hierarchy and can be used with a single volume (e.g., flow volume) representing the space to be meshed. “Initial results of Parallel mesh generation are truly astounding,” says Joe Walsh, VP of Business Development at Simmetrix Inc. “With a hundred million cells now being meshed in about 10 minutes, a paradigm shift for large scale analyses is inevitable.” Parallel MeshSim is available for licensing by software vendors as part of the Simulation Modeling Suite and is supported on Linux, Sun, and Mac OS X platforms.

About: NAFEMS
NAFEMS is a not for profit organisation aimed at promoting best practices and also fostering education and awareness in the engineering analysis community. In line with its objectives to promote the effective use of simulation technologies, NAFEMS is continually seeking to create awareness of new analysis methodologies, deliver education & training, and stimulate the adoption of best practices and standards by offering a platform for continuous professional development.By the late 1970s and early 1980s, as computing power became more widely available, increasingly industry was starting to solve practical engineering problems using finite element analysis techniques. There was however considerable concern that the accuracy of the methods, and software implementations, required to be verified in order to allow the results to be effectively used. Following extensive lobbying, by industry and academia, the UK Government's Department of Trade and Industry (DTI) set up, and funded, a project within the National Engineering Laboratory (NEL), based in East Kilbride, Scotland, to investigate the issues. As a result the National Agency for Finite Element Methods and Standards, quickly shortened to the acronym NAFEMS, was founded as a special interest group in 1983 with a specific objective namely: "To promote the safe and reliable use of finite element and related technology" In order to keep engineers abreast of the latest developments in the Analysis World the quarterly magazine BENCHmark was launched by NAFEMS in July 1987. After seven years of seed funding by the UK government, and with the support of its industrial members, the decision was taken to launch NAFEMS Ltd as an independent not-for-profit company, owned by its member's in 1990. The company celebrated its 10th Anniversary in 2000, and has developed both the scope of its technology focus and its membership well beyond the original vision. Today NAFEMS and its members are involved in many different types of engineering simulation covering both products and processes. Membership continues to grow, now exceeding 700 corporate members in over 30 different countries. Steering groups have been set up in the UK, France, Germany, and the USA to co-ordinate local activities and interaction with members. |
