Grouped element-by-element iteration schemes for incompressible flow computations. (English) Zbl 0803.76065

Summary: Grouped element-by-element (GEBE) iteration schemes for incompressible flows are presented in the context of vorticity-stream function formulation. The GEBE procedure is a variation of the EBE procedure and is based on arrangement of the elements into groups with no inter-element coupling within each group. With the GEBE approach, vectorization and parallel implementation of the EBE method becomes more clear. The savings in storage and CPU time are demonstrated with two unsteady flow problems.
