Hi all, In OpenFOAM 1.4 a n
 
Hi all,

In OpenFOAM 1.4 a new wallfunction (nutStandardRoughWallFunction) is available. Does someone know how/where to specify the parameters needed (roughnessHeight, roughnessConstant and roughnessFudgeFactor) for these wall functions?
Starting from a working case I have changed the physicalType of the wall from wallFunctions to nutStandardRoughWallFunction and added

roughnessHeight roughnessHeight [0 0 0 0 0 0 0] 1;
roughnessConstant roughnessConstant [0 0 0 0 0 0 0] .3;
roughnessFudgefactor roughnessFudgeFactor [0 0 0 0 0 0 0] 1;

to the turbulence properties, but nothing changes in the results. Does anyone know what I am doing wrong?

Regards,

Lourens Aanen.
