[petsc-users] SNES and ghosted vector of unknowns

[Dominik Szczerba]

I am using SNES to solve a simple nonlinear system.
My vector of unknowns (x) is ghosted, and before (i.e. with my own
home brewed nonlinear solver) I had to always update the ghosted
values after a linear solve with ksp. How can I now force the update,
if I am not calling ksp myself?

Thanks for any hints,

Dominik
