Yes, these are the two adjacent cells, since you need this information when 
computing jump terms.

Would you be interested in adding this information to whatever place you 
thought should have said this? (I.e., where you looked for it?)

[deal.II] Usage of MeshWorker::mesh_loop for DG methods

2019-01-25 Thread 'Maxi Miller' via deal.II User Group
When using mesh_loop for discontinuous galerkin, I have to add two 
additional functions, boundary_worker and face_worker. When calling 
face_worker, it gets two cell-iterators as parameter. Are those two cells 
automatically neighbours, or do I have to check that in the worker itself? 
I could not find that in the documentation.
Thanks!
