[petsc-users] DMPlex and MatSetValuesLocal

[Abhyankar, Shrirang G.]

Matt,
   Does MatSetValuesLocal work with a matrix that is created with DMPlex?
Well, actually I am using DMNetwork. I am getting the following error
because ISLocalToGlobalMapping mat->rmap->mapping and mat->cmap->mapping
are not set on the matrix. Perhaps I am not setting up something correctly?

Shri
