Partitioning is the process of dividing the mesh into a number of ‘partitions’ each of which may be solved on a separate processor. Several partitioning methods have been developed, but most are based on recursive bisection and differ only in the bisection step. The original mesh is first decomposed into two meshes of approximately equal size. The decomposition is then repeated recursively until the required number of partitions is obtained. The following diagram shows this process.
