Multigrid is a popular solution method for the set of linear algebraic equations that arise from PDEs discretized with the ΓΏnite element method. The application of multigrid to unstructured grid problems, however, is not well developed. We discuss a method, that uses many of the same techniques as t
## Abstract This paper presents a numerical study of the 3D flow around a cylinder which was defined as a benchmark problem for the steady state NavierβStokes equations within the DFG highβpriority research program __flow simulation with highβperformance computers__ by Schafer and Turek (Vol. 52, V
A stress recovery procedure, based on the determination of the forces at the mesh points using a stiffness matrix obtained by the finite element method for the variational Lagrange equation, is described. The vectors of the forces reduced to the mesh points are constructed for the known stiffness ma
A stress recovery procedure is presented for non-linear and linearized problems, based on the determination of the forces at the mesh points using a stiffness matrix obtained by the finite element method for the Lagrange variational equation written in the initial configuration using an asymmetric P
