Hi!
I'm modeling gas flow trough statical mixer. I'm using Pascals in my boundary conditions (dimensions [1 -1 -2 0 0 0 0] . I'm using swak4foam to calculate pressure drop between inlet and outlet:
Code:
    pressureDrop
    {
        type patchExpression;
        variables ( 
            "pOut{patch'outlet}=sum(p*area())/sum(area());"
            "inArea=sum(area());"
        );
        accumulations (
           sum
        );
        patches (
            inlet
        );
        expression "area()*(p-pOut)/inArea";
        verbose true;
    }
The problem is that the calculated pressure drop is much less than expected. Which units is applied in swak4foam output?
OF 2.1.1
solver: rhoSimplecFoam

Thanks
