get no outflow / BC problem
Hi,
I have a geometry with different inlets and just one outlet. I want to fix the velocity at all inlets. Iam working with TwoPhaseEulerFoam. When i plot U glyphs with paraview there is no outflow at my outlet and i dont know why. I tried different BC but it is always the same... my actual BC for U and P are defined like that:
Ua/b
Code:
OBJECT_Inlet1
{
type fixedValue;
value uniform (0 0 0.1);
}
OBJECT_Outlet
{
type inletOutlet;
value uniform (0 0 0);
inletValue uniform ( 0 0 0 );
}
OBJECT_wall
{
type fixedValue;
value uniform (0 0 0);
}
OBJECT_inlet2
{
type fixedValue;
value uniform (0 0 0);
}
OBJECT_inlet3
{
type fixedValue;
value uniform (0 0 -0.5);
}
OBJECT_Wall2
{
type fixedValue;
value uniform (0 0 0);
}
P:
Code:
OBJECT_Inlet1
{
type zeroGradient;
}
OBJECT_Outlet
{
type fixedValue;
value uniform 0;
}
OBJECT_wall
{
type buoyantPressure;
value uniform 0;
}
OBJECT_inlet2
{
type zeroGradient;
}
OBJECT_inlet3
{
type zeroGradient;
}
OBJECT_Wall2
{
type buoyantPressure;
value uniform 0;
}
Hope you can tell me what is wrong with my BC. |
