boxToCell alternatives
 
I want to simulate a compressible flow inside a cylindrical pipe what alternatives that I can use instead of boxToCell to setFields. I'm still new in openFoam

Hi,

As setFields uses topoSetSource for selecting cells, you can use examples from topoSet utility (with certain modifications), you can find them in $FOAM_APP/utilities/mesh/manipulation/topoSet/topoSetDict file.

Below is an example of cylinderToCell source usage in setFieldsDict file:

Code:
regions
(
    cylinderToCell
    {
        p1 (0 0 -1.0);
        p2 (0 0  1.0);
        radius 0.35;

        fieldValues
        (
            volScalarFieldValue T 393.15
        );
    }
);
