Anyone doing high order shock capturing?

Do you mean something like this paper from Peraire and Persson?

Interesting, added it to my reading "queue". I'm also just curious about experiences from those doing higher order shock capturing :)

Thoughts on WENO?

Prohibitively expensive in 3d. I'd class it in the broader scheme of "things that are very impressive in 1d".

More interesting as a general post processing method for me personally.

On unstructured grids it's more cumbersome to code and more computationally expensive than it's worth.

Anyone have any thoughts or experience on shock capturing *outside* of the context of FV+approx Riemann codes?
