[petsc-users] matrix-free preconditionning of FGMRES

I am new to PETSc and I am interested to use the nonlinear solver in a CFD
code for low speed compressible fluid.

According to some papers, it seems that GMRES (or any other Krylov method)
could be used to precondition FGMRES in a way that is completely matrix-free.
Is it something possible with the fgmres implementation provided by PETSc ?
