Prepartitioning as a way to mesh subdomains in parallelGaltier, Jerome and Paul Louis George5th International Meshing Roundtable, Sandia National Laboratories, pp.107122, October 1996


Abstract We introduce a new method to mesh a physical domain in parallel. Given a domain defined by a set of boundary facets, we construct a separator of it. As a result, we obtain several subdomains, each of them being defined by a set of boundary facets. Naturally, the separation step can be applied recursively to increase the number of subdomains, or to reduce the size of one subdomain. Then, a Classical mesh generator is applied to achieve the computation. Along with the theoretical background that allows to mesh such a separator (this process is called prepartitioning), we show how the method performs on a large set of industrial examples. Some parallel simulations have been done, and the results for large examples are promising.
