Reynolds stress transport model with elliptic relaxation
 
Dear FOAMers,

The number of Reynolds Stress Transport Models implemented in OpenFOAM seems to be relatively small (only LRR and LaunderGibson as I know of). Both are high-Re formulation, i.e. wall functions should be used.

For my research, I need wall-resolved RSTM. Therefore, I implemented two formulations of RSTM with elliptic relaxations/blending, i.e.:

Durbin:
Durbin Elliptic Relaxation Model (Durbin1993)
ManceauHanjalic:
Hanjalic Elliptic Blending Model (Manceau2002)

My colleague M. Wild reviewed the code, cleaned up the style, and made up a lot of improvements. Now, the code is hosted on github, together with a solver and an example case. The address is:

https://github.com/xiaoh/EllipticRSTM

You can obtain them by:

git clone git://github.com/xiaoh/EllipticRSTM.git

More information please see the README and the code itself. Any feedback or improvement is appreciated!
