Hi,
I just learn openFOAM for a short time. And a problem has been bothering me for a week. Why my setFields is not work. My setFields is that.
defaultFieldValues
(
volScalarFieldValue alpha.water 0
);
regions
(
boxToCell
{
box (0 0 0) (1.0 0.1 0.1);
fieldValues
(
volScalarFieldValue alpha.water 1
);
}
);

This case is a channel od dimensions 1.00m*0.10m*0.15m(length, width, height). No matter how to change the boxToCell, there is nothing to change. Only the inlet is water. But i want a half water and the rest is air. I have seen many posts here. But there is still no solution. I really nead help.
Thank you!
