The multigrid strategy we present here is adapted from the generalized finite volume agglomeration multigrid algorithm we have developed recently for the solution of the Euler equations. We now focus on the Poisson's equation. A strategy is defined by introducing a correction factor for the diffusive terms and some illustrating results are given. %G English %2 https://inria.hal.science/inria-00074727/document %2 https://inria.hal.science/inria-00074727/file/RR-1946.pdf %L inria-00074727 %U https://inria.hal.science/inria-00074727 %~ INRIA %~ INRIA-SOPHIA %~ INRIA-ROCQ %~ INRIA-RRRT %~ INRIASO %~ INRIA_TEST %~ TESTALAIN1 %~ INRIA2 %~ LARA
