I think the cell integrates over what its shape dictates. In the case of Neumann boundaries you want to integrate over surfaces. If you want to integrate over a volume...

- Coordinate Elements: Yes. The GeometryMesh will be very similar to the MeshFem replacing ElementCollections with Coordinate Elements (the mesh may have a method that returns a corresponding function space)....

We think that at this point coordinates and dofs are separated as good as possible without introducing major changes. - Coordinate Element and DofElement have still the same base class...

Change the name of the node selection routine NodeAtAxis to something different since it is essentially doing a NodeAtCoordinate but with with only some of the coordinates fixed. Say in...

The reason why this problem showed up was the implementation of an example of the scaled boundary element method. There the differential operator/B-Matrix is splitted into a sum B1+B2 where...

I am not sure if this is going into the right direction: The problem of accidently getting Coordinate Nodes because you forgot to provide a DofType is solved by renaming...

Don't wait for me, just go on.

Good! If I understand it correctly, based on the current implementation of the assembler: the loops over cells and dof types are then done via generator.next(). And the entry the...

I think the concept of a simple reference element of different shapes should lead to a simple object that describes just this. It has nothing to do with integration, interpolation,...

Yes. Since the test involves a simple wave equation and the solution is known it is probably enough to do only some time steps and then compare the result. In...
