On modified block SSOR iteration methods for linear systems from steady incompressible viscous flow problems (Q613228)

The paper is concerned with the presentation of the block symmetric successive overrelaxation (SSOR) and a modified block SSOR iteration methods, based on the special structures of the coefficient matrices arising in numerical solution of two-dimensional steady incompressible viscous flow problems in primitive variable formulation. The authors present a theoretical analysis which shows that, under certain conditions, these methods are convergent for the nonsymmetric systems arising from the discretization of the above mentioned problems.
