[petsc-users] FIELDSPLIT preconditioner in parallel

[Rossi, Simone]

Hello,

I'm trying to use PCFIELDSPLIT to solve a two by two block system and it is working pretty nicely (thanks a lot for that!).

I'm still having some issues in parallel though: the ksp solver throws an error when one of the fields does not have DOFs  on a processor. Is there a way  around it?

Thanks a lot for the help,

Simone
