Hello dear Foamers,

I am new in OF, my question is that :
How is it possible to combine two boundary conditions at inlet?

I need to implement groovy BC to apply a boundary layer velocity profile at the inlet of my domain. Something like this:

inlet  
   {      
   type            groovyBC; 
        variables        "u_f=0.0239;z0=0.0000333;K=0.41;vel=(u_f/K)*log(pos().z/z0)*normal();";      
   valueExpression "-vel";    
 }

On the other hand, I want to apply velocity fluctuations using LEMOS inflow turbulence generator:

inlet     {  
       type            decayingTurbulenceInflowGenerator;
         direction       1;      
   LField          uniform 1;      
   RField          uniform (0.1 0 0 0.1 0 0.1);   
      refField        uniform ( 20 0 0 );     
    value           uniform ( 20 0 0 );    
 }

How can I combine these two boundary conditions at inlet?
Thanks

Any one willing to help? Am I asking something too basic?!
May some one show me the principles at least??
Thanks.
