Boundary Conditions RANS rhopisofoam
Dear CFD friends,
I am very new to OpenFoam. I would like to initialize alphat, epsilon, k mut, omega and R for rhopisofoam RANS. Could someone help me please?, Thank you very much. 
Can you please post details about your case and what kinda help you need?? i mean in calculating or setting up or whatever..

Dear CFD friend,
I have a duct ( inlet, outlet, walls) and the velocity at the inlet is 10 m/s and the pressure at the outlet is 0. If you need more information I can tell you more. Thank you very much. 
Well, i am also not very much sure about this, as i am also facing same problems, but would like to tell you what i know. It might help you nevertheless.
alphat =turbulent thermal diffusivity R= Reynolds stress tensor eps = turbulent dissipation rate omega = specific turbulent dissipation rate k = turbulent kinetic energy I think the variables you need to specify depend upon the turbulence model you use. Say you are using keps model then you will need to specify k and epsilon and alphat. And in case you need to calculate the actual values for the parameters, you can use the formulas used widely. See following link: http://jullio.pe.kr/fluent6.1/help/html/ug/node178.htm I dont know about specifying values for alphat and R.:( Hope this helps.:o just got some more info :) Please see this post, you will get more info: http://www.cfdonline.com/Forums/openfoamsolving/79323solversubsoniccompressibleturbulentflow17a.html#post272288 
Thank you very much !!!.
