parabolic velocity profile with fluctuations (groovyBC?)

I would like to implement a parabolic inlet velocity profile, with fluctuation scale specified (like in turbulentInlet).
I tried using groovyBC as below (since I think turbulentInlet allows flat profile only), but am not sure how to specify the fluctuation scale (if possible?): type groovyBC; variables "yp=pts().y;minY=min(yp);maxY=max(yp);para=-(maxY-pos().y)*(pos().y-minY)/(0.25*pow(maxY-minY,2))*normal();"; valueExpression "15*para"; value uniform (15 0 0); Has any one encountered a similar problem or has suggestions on how to proceed? I tried searching the forum but am not sure if including fluctuation scale in groovyBC has been discussed (though there were some posts on parabolic profile). If not groovyBC, is there another way to implement this? I use OF 1.7.1 Many thanks, amit PS. This implementation is required as we are trying to match the experimental conditions which show a parabolic inlet profile and high fluctuations as well...
