Application of the Multigrid Technique to Solve the Pressure Correction Equationof Incompressible Flow

摘要

An implementation of a multigrid technique to solve the pressure correctionequation of incompressible flow is described. Two methods, full approximation storage (FAS) and multigrid (MG), were investigated and compared with a single level (SL) iteration technique. Only simple V-cycles were used. The solutions of the equations were always iterated by using the Gauss-Seidel method (GS).
