Supposed, I use DM to construct my grid. I would like to know if DM can 
be used to update the ghost values easily?

If I can use staggered grid, does it mean I have to create 3 DM grids 

Also, how can I solve the momentum eqn involving u,v,w using KSP?

What examples can I follow for the above requirements?

Thank you.

Yours sincerely,
