Draft: Feature/quadrature volume average
What this MR does / why does DuMux need it:
This is a first draft how we could realize volume averaging by simply defining a quadrature rule on entity intersections
-
Cherry-pick example of permeability averaging to demonstrate the simplicity of this approach -
Add PQ1Bubble scheme to also interpolate at quadrature points, yielding more accurate results. -
Maybe don't inherit from Dune::QuadraturePoint
since thereposition()
relates to local position. -
Use iterative solver
