nut wall functions for incompressible RAS
Hi guys! I'm new to openFOAM, and it's my first thread here. :)
I'm trying to run an existed openfoam case (it is written in 1.6.0) using openFOAM 2.1.0. I'm using LaunderSharmaKE turbulence model. The 0/nut file has some entries as:
value uniform 0;
I guess this is where the problem generates. When I run simpleFoam solver, it gives out the error message:
--> FOAM FATAL IO ERROR:
Unknown patchField type nutWallFunction for patch type wall
Valid patchField types are :
I checked $FOAM_SRC/turbulenceModels/incompressible/RAS/derivedFvPatchFields/wallFuntions, there is a folder named nutWallFunctions, inside which list many wall functions.
So my question is which wall function I should use to replace the "nutWallFunction" entry. Would anyone give me some hints?
Thanks a lot!
I am facing exactly the same problem. I am trying to run a case, which works in OF1.7.x, in OF2.1.1 and get.
Any suggestions regarding the wallfunction that should be used since "nutWallFunction" is no more available?
Try nutkWallFunction or nutUWallFunction; nutkWallFunction replicates OF 1.5.x behaviour. If you look at the code you can see that the different between them is the way the yplus is calculated. The doxygen documentation is your friend here:
Thanks for the quick response.
So the initial condition for nut is given in the same way:
Yes. When in doubt, find a working case from the tutorials that has something similar to what you want, then copy that.
