I'm using OF3.0 with RASModel kOmegaSSTSAS which used to be classified as an LES model. When I run pimpleFoam it complains about delta not being defined. The case worked fine with OF2.3.1. Any thoughts what I'm doing wrong here?

--> FOAM FATAL IO ERROR: 
keyword delta is undefined in dictionary "/0_solid_10ms_OF3/constant/turbulenceProperties.RAS.kOmegaSSTCoeffs"

file: /0_solid_10ms_OF3/constant/turbulenceProperties.RAS.kOmegaSSTCoeffs from line 0 to line 0.

    From function dictionary::lookupEntry(const word&, bool, bool) const
    in file db/dictionary/dictionary.C at line 442.

Hi,

If you read error message:

delta is undefined in dictionary .../turbulenceProperties.RAS.kOmegaSSTCoeffs

you see, delta keyword should be defined in kOmegaSSTCoeffs dictionary. You do not have it in turbulenceProperties.
