Hi guys,

i want to create a linear velocity profile at the inlet patch for simulating couette flow in a channel with less computational effort, therefore I tried following code:

inlet
{
type groovyBC;
variables "maxVel=1;yp=pts().y;minY=min(yp);maxY=max(yp) ;";
valueExpression "((maxY-minY)/maxVel)*normal()*time();";
value uniform (1 0 0);
}

Is this right? I already set the maximal velocity in the U description of a moving wall (velocity = 1 m/s). Is there an option to link the groovyBC (maxVel part) with this boundary condition, eg: "maxVel=mag(U)@movingWall";
