[petsc-users] grid sequencing & DMComposite

[Gideon Simpson]

I’m using a DMCompsosite along with grid sequencing and here’s what I’m trying 
to accomplish.  After running the SNES solve, I’d like to evaluate the residual 
on the refined grid, on each piece of the DMComposite.  How do I get a DM for 
the refined grid which I can then use with DMCompositeGetLocalVectors in order 
to get each piece of the problem?  Or is there a better way?
