[petsc-users] Parallel FEM code using PETSc

sorry, I just noticed that this may not have been answered to your full 
satisfaction yet. Please have a look at SNES, ex62, located in
$PETSC_DIR/src/snes/examples/tutorials/ex62.c

Short description:
Stokes Problem in 2d and 3d with simplicial finite elements.
We solve the Stokes problem in a rectangular domain, using a parallel 
unstructured mesh (DMPLEX) to discretize it.

Best regards,
