[petsc-users] Computing Vector Norm Field wise

[Luc Berger-Vergiat]

Hi all,
I am using the fieldsplit/DM facility to work on a multiphysics problem.
I would like to get some field dependent convergence information.
Is there something similar to the VecStrideNorm function that can 
compute a residual for each field defined in the DM?
Or should I use the DM to extract subvectors and compute their norms?
