# Implicit/Multigrid Algorithms for Incompressible Turbulent Flows on Unstructured Grids

@inproceedings{Anderson1996ImplicitMultigridAF, title={Implicit/Multigrid Algorithms for Incompressible Turbulent Flows on Unstructured Grids}, author={W. Kyle Anderson and Russ D. Rausch and Daryl L. Bonhaus}, year={1996} }

An implicit code for computing inviscid and viscous incompressible flows on unstructured grids is described. The foundation of the code is a backward Euler time discretization for which the linear system is approximately solved at each time step with either a point implicit method or a preconditioned generalized minimal residual (GMRES) technique. For the GMRES calculations, several techniques are investigated for forming the matrix?vector product. Convergence acceleration is achieved through a… CONTINUE READING
