@ -3,16 +3,19 @@ Short overview of the changes to have cyclics split into two halves.
Cyclics
-------
The two cyclic halves are now split like processor patches. There should be no
difference in running. Just some of the reasons for switching over from the
old 2-halves in one patch:
- face ordering after topological changes becomes much easier since we
now preserve what half the face comes from.
- cyclic handling becomes more consistent with processor handling and can
quite often be handled in the same condition.
difference in running.
Advantages:
- decomposed cyclics can now be handled properly. It just needs to preserve
the cyclic patch it originates from.
- We can now construct a table of global transformations and handle
points/edges/cells with transformations.
- face ordering after topological changes becomes much easier since we
now preserve what half the face comes from.
- cyclic handling becomes more consistent with processor handling and can
quite often be handled in the same condition.
- transformation tensors now become single entry.
The disadvantages:
- a patch-wise loop now might need to store data to go to the neighbour half
since it is no longer handled in a single patch.
