Hello Foamers,

ich got a problem with the boundary condition settings. First of all, i use OpenFoam 4.0.1 und the solver is interFoam. I have used blockMesh to create a back ground mesh und used topoSet and createBaffles to create an internal face, which will be defined as patch. Now i want water comes from this patch with defined velocity or flowrate. I tried to use the following BCs, but no success. I attached a pic so that you can understand better. Could anyone please hlep? I've worked on it for long time and it bothers me very much.

alpha.water: 
type      inletOutlet;
inletValue 1;
value       1;

p_rgh:
type    totalPressure;
p0      1e5;

U
type fixedValue;
value uniform(0 0 -5e-4);
