Talk:Options for edge/face data
Turns out the user/developer who had with this use case has developed a new plot for it, but it hasn't made it into the hands of users. I won't be able to get good information on use cases until it hits users, unfortunately...

Generic representation of fluxes
If a flux is represented as a scalar value then it also implicitly defines a direction. Take this simple 2d structured example.
i ------------- | | | | | | j | | | ------------- F1 F2 F3
Say the Flux at F2 = 2.0. What does this mean? Does it mean flowing left to right or right to left? If flux directions are well defined, then I believe a summing of the fluxes over a zone to create zonal value gives a user good intuition about the physical process. Perhaps pick could provide the edge values if the details of each edge need to be presented.
That said it is easy to impose a direction for a structured code - but what about for unstructured codes?
