Hi,

I am trying to modify the standard kEps model to attain the influence of the buoyancy related turbulence.

I followed a few different methods however all seemed to fail.

1- Using readGravitationalAcceleration.H :
--> FOAM FATAL ERROR:
request for dictionary gravitationalProperties from objectRegistry region0 failed
available objects of type dictionary are
4
(
RASProperties
fvSchemes
fvSolution
transportProperties
)

2 - Reading from transportProperties:
--> FOAM FATAL ERROR:
LHS and RHS of + have different dimensions

The solver works fine with the standard kEps so I don't think that I have to change the solver or B.C's.

3- Creating a file called "g" and reading via lookupObject<uniformDimensionedVectorField>("g") :
Unknow type uniformDimensionedVectorField

4- Linking as a field by lookupObject<volVectorField>("g") :
gives an error during the runTime since g is a uniformDimensionedVectorField

I guess one other way would be to use a hard-coded vector but I don't want to do that. Any help is appreciated.

OF version: 1.6.x
OS: CentOS 5

Thanks a lot,
Fatih.
