Unknown RASModel type kkLOmega

derekm · March 14, 2015, 10:15

I'm getting this error it seems quite a few of the turbulence models are missing (openFoam 2.3.1 OpenSuse 12.3)
what is going wrong? This in case where kEpsilon has worked successfully

Code:

Selecting turbulence model type RASModel
Selecting RAS turbulence model kkLOmega
[0] 
[0] 
[0] --> FOAM FATAL ERROR: 
[0] Unknown RASModel type kkLOmega

Valid RASModel types:

10
(
LRR
LaunderGibsonRSTM
LaunderSharmaKE
RNGkEpsilon
SpalartAllmaras
kEpsilon
kOmegaSST
laminar
realizableKE
v2f
)

i was expecting this list as taken from the makefiles

Code:

laminar
kEpsilon
RNGkEpsilon
realizableKE
kOmega
kOmegaSST
SpalartAllmaras
LRR
LaunderGibsonRSTM
LaunderSharmaKE
qZeta
LienCubicKE
LienCubicKELowRe

LienLeschzinerLowRe
LamBremhorstKE
kkLOmega
v2f

Hi,

Deducing from the list you have posted, you are using compressible RAS models, while kkLOmega is incompressible RAS model.

spot on!

Im using CHTmultiregionsimpleFoam and for some reason I though it used incompressible RAS, just checked the makes files for chtmrsf and its compressible.

I shall read http://www.tfd.chalmers.se/~hani/kur...inesqFoam7.pdf again...
