[petsc-users] To store the RHS vector b of KSPSolve.

[Xuefei (Rebecca) Yuan]

Hello all,

I have a piece of code that need to store the RHS vector b of the ksp object 
via vecview.

However, the routine is like:


        ierr = DMMGSetSNESLocal(dmmg, FormFunctionLocal, 
FormJacobianLocal,0,0);CHKERRQ(ierr);
        ierr = DMMGSolve(dmmg);CHKERRQ(ierr);

The rhs evaluation is in FormFunctionLocal(), how could store the rhs vector b?

Thanks very much!

Cheers,

Rebecca
