[petsc-users] working with different size of arrays in a single DA

[ilyas ilyas]

Hi,
May be, It is a simple question, but I am little bit confused.
If I have two different size of arrays (one is cell-based which is from 1 to
N,
other one is face-based which is from 1 to N+1).
How can  I create and work with them within a single DA structure,
for example in evaluating a function or setting up a matrix ?

Regards,
Ilyas.
