Hi I am filling the local vector from dm , has a section layout. The thing is I want to know how I can see the field variable values defined on edges, the staggered grid. In fact, Whenever I output to VTK in preview, I would be able to see the main grid. But the values which are defined on edges, I could not see them and that makes me unsure about the way I fill the local vector. How I would be babe to check the field value on staggered grid?
