Result line fit really good.
And it's much more better than 2D calculations of the same airfoil

This year (2013) has been an interesting one for me, regarding OpenFOAM. Even beyond the amazing features that OpenFOAM 2.2 brought to the world (at least to my world) and everything that I keep discovering about it.

This blog post is about the various threads/posts were I took the time to diagnose what was specifically wrong with the case and where the bad results are astonishingly wrong... simply because the details were not easily seen. The list might get updated along time, as I...

Hi Tom,

This sounds like an interesting problem! Ignoring the wave space issue for a moment, I think you need to first cast the problem as a 2D surface using either the finiteArea machinery of 1.6-ext, or the thin film model in 2.2.x (see reactingParcelFilmFoam).

The wave space issue is a bit more complex and I don't have a good recommendation for an elegant solution. Brute force for a fixed number of wave-space bins would be doable, but ugly. What is the typical...
