This paper investigates different approaches to treat chemical and turbulent production terms on coarse grids in order to enable convergence. A full coarsening four-level nested multigrid method is used for all conservation equations including those of turbulence and species transport. Strong convergence accelerations are achieved by a local source term-dependent damping of the restricted residual error. Several test cases with and without combustion demonstrate the accuracy of the proposed multigrid algorithm. \(\copyright\) Academic Press.
