What FE discretization? We don't recommend using files as part of your workflow, but if you're just experimenting, you could start with src/ksp/ksp/examples/tests/ex11.c which solves a Q1-P0 Stokes problem From Underworld by reading the blocks in as matrices. So start there and let us know how it goes.
