[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?
