Hi everyone,

I have simulated a single droplet falling in a chamber by interDyMFoam. I can see the drop is falling properly in the chamber. Then in order to study the effect of turbulence on the droplet, I have added a horizontal plate inside the chamber. I have set B.Cs of the plate similar to the other walls. But this time the droplet doesn't move. I think the plate B.Cs especially the bottom part of it make the trouble. I will appreciate for any suggestion for other kind of B.Cs that may solve the problem. I have attached mesh view. p-rgh boundary conditions are as following:


internalField uniform 0;

boundaryField
{
plateWall
{
type fixedFluxPressure;
value uniform 0;
}
leftWall
{
type fixedFluxPressure;
value uniform 0;

}

rightWall
{
type fixedFluxPressure;
value uniform 0;

}

down
{
type fixedFluxPressure;
value uniform 0;
}
up
{
type totalPressure;
p0 uniform 0;
U U;
phi phi;
rho rho;
psi none;
gamma 1;
value uniform 0;
}
front
{
type fixedFluxPressure;
value uniform 0;

}
back
{
type fixedFluxPressure;
value uniform 0;
}

}

Thanks.
