This PR adds a routine for polynomial based reconstruction in SharpClaw. In detail,

  • 4th and 6th order Polynomial reconstrcution
  • 8th and 10th order reconstruction are also included but have not been fully tested yet
  • renames "weno_order" to "reconstruction_order"
  • deallocate calls for WENO5 and Poly_comp
  • sets number of ghost cells for either Weno or Poly in solver
  • documentation

Just a reminder for anybody testing this -- you'll need to rebuild:

cd clawpack
pip install -e .

Just a note: renaming weno_order to reconstruction_order is backward-incompatible, but it is a small enough change that I think it's okay for this to go into 5.3.

@ketch, if needed for 5.4 I can add backward-compatibility...

Maybe that's a good idea; we can just emit a warning saying that the old attribute will be deprecated in future versions.

I just merged in the fix for the doctests (from master) so this is passing now.


Order of the WENO reconstruction. From 1st to 17th order (PyWENO)
Order of the reconstruction. From 1st to 17th order (PyWENO), and from
4 to 10 (even) in Poly

This should say

From 5th to 17th order (odd) for WENO reconstruction and from 4th to 10th order (even) for piecewise polynomial reconstruction.

Ah, I just noticed that it's wrong in master...

This looks great and will be very useful. It would of course be nice to have:

  • A test that uses the new reconstruction
  • At least some comments at the top of poly.f90 documenting the functions there.

I made some modifications to it in my fork and rebased it... I haven't got
time to finalize testing. I will update it soon.

Thanks for the update. Would you like this included in the 5.3.1 release or would this be better for the 5.4.0 release?

If @sanromd can add a test or two soon, it would be great to get this into 5.4.0. It probably shouldn't go into 5.3.1 since it's a major feature and 5.4 is coming very soon anyway.
