[petsc-users] Field split questions

[Colin McAuliffe]

Hello all,

When using PCFieldSplitSetIS to define splits within splits, should  
the IS contain indices in the original matrix or in the next highest  
split level?

Also, my matrix is in aij format but one of the sub fields has a block  
diagonal structure. Is it still possible use block jacobi on this field?

Thanks and all the best
Colin
