Hi All,
I am relatively new
Hi All,
I am relatively new to openFoam.. I just finished solving the tutorial for SimpleFoam, but I would like to know how the simple foam is used for laminar flow equations as the k epslon terms are not there for laminar flow right... So how do we change the code to make it work for laminar flow... Kindly give your suggestions in this regard. Regards Vishal |
In the constant/RASProperties
In the constant/RASProperties file, set the RASModel to 'laminar' instead of 'kEpsilon' and turbulence to 'off' instead of 'on'.
When running the case, you should then see these messages before the first time step: -------------- Selecting incompressible transport model Newtonian Selecting RAS turbulence model laminar -------------- To find out all the available options, set the 'RASModel' to some arbitrary text, say 'scooby_doo' and then run simpleFoam. The code will then return something like: Unknown RASModel type scooby_doo Valid RASModel types are : 15 ( NonlinearKEShih kEpsilon realizableKE LienCubicKELowRe LienLeschzinerLowRe LaunderSharmaKE laminar SpalartAllmaras LienCubicKE LamBremhorstKE RNGkEpsilon LRR QZeta LaunderGibsonRSTM kOmegaSST ) Now, you have a full list of available turbulence models! |
What does turbulence when set
What does turbulence when set to "on" or "off" while selecting RASModel laminar mean?

Hi Srinath,
Thanks a lot fo
Hi Srinath,
Thanks a lot for the reply. I would like to know if I select these two options, then what should we do for the RASModel transport properties... as there are many property values like kepsilon etc.. similarly in the fvsolution all these k-e values are present.. wat should one do to these parameters... Kindly let me know... Regards Vishal |
Well, they're not used to my k
Well, they're not used to my knowledge. So they are just ignored for laminar flow.
