Combining two boundary conditions
 
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:

Code:
Code:

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:

Code:
Code:

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
