Hi Patrick, It worked, thank you!

Something like: PCMGSetNumberSmoothDown<https://www.mcs.anl.gov/petsc/petsc-3.8/docs/manualpages/PCMG/PCMGSetNumberSmoothDown.html#PCMGSetNumberSmoothDown>(PC<https://www.mcs.anl.gov/petsc/petsc-3.8/docs/manualpages/PC/PC.html#PC> pc,PetscInt<https://www.mcs.anl.gov/petsc/petsc-3.8/docs/manualpages/Sys/PetscInt.html#PetscInt> n, PetscInt<https://www.mcs.anl.gov/petsc/petsc-3.8/docs/manualpages/Sys/PetscInt.html#PetscInt> l) In this way I could, for example set 3 smoothing steps on level 1 and 7 smoothing steps on level 2. Thank you! Pietro
