Hi there,

I'm trying to evaluate gas dispersion performance of sprayFoam and so I wanted to initialize a cloud of pure NH3 in a room filled with air (77% N2, 23% O2). I set up the setFieldsDict as follows:

defaultFieldValues
(
volScalarFieldValue NH3 0
volScalarFieldValue O2 0.23
volScalarFieldValue N2 0.77
);

regions
(
boxToCell
{
box (0 0 0) (0.1 0.1 0.1);
fieldValues
(
volScalarFieldValue NH3 1
volScalarFieldValue 02 0
volScalarFieldValue N2 0
);
}
);


The setFields-Function works fine - no warnings, no errors - but in the end I don't get these fields set up. So what's wrong?

Well, it turned out to be the mesh. There was no cell center inside the small box, because the cells where to large. Or something like this.
