Added boundary flux and boundary source #11

Closed mattlie82 closed 3 years ago

mattlie82 commented 3 years ago

Added bflux and bsource to describe surface fluxes and (fixed) sources.

The example in Example311_HeatEquation_BoundaryDiffusion.jl still shows problems (artefacts near boundaries). Moreover, it is currently not possible to describe anything but homogeneous Neumann boundary conditions for the surface fluxes. This needs additionally functionality in ExtendableGrids.jl.

Tests fail due to allocations during assembly in boundary face loop.

Ok, kann es sein dass Du ein modifiziertes ExtendableGrids nutzt ? Dann bräuchte erst einmal den PR dort.

I did, see https://github.com/j-fu/ExtendableGrids.jl/pull/8
