The approach is based on a cell-centered multigrid algorithm, which combines a piecewise constant interpolation and the restriction operator by Wesseling/Khalil with a line-wise relaxation procedure. A local Fourier analysis is performed for the case of a Cartesian uniform grid. The method shows a robust convergence for different full tensor coefficient problems and several rough quadrilateral grids.25 p.application/pdfeng© Springer Nature Switzerland AG 2020Darcy problemLocal Fourier analysisMultigridMultipoint flux approximationRough gridsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
