Default setFields does not recognize inlet patch

Hello everyone,

I created a mesh from a DEM of a river with snappyHexMesh. I did the spillway tutorial of openFoam and I want to apply the interFoam solver at my case. My problem is the following: in the setFieldsDict, I created a box around a part of my geometry, including the inlet patch. The setFields utility works, but it does not set the alpha values to 1 at the inlet and at the atmosphere patch , it does set the alpha values to 1 at the walls and at the internal mesh. I checked already the bounding box, it is large enough to cover the region.

volScalarFieldValue alpha.water 0
box (-100 -10 -10) (100 20 30);
volScalarFieldValue alpha.water 1

Any suggestions what might be wrong? How can I fix it?

Thank you for your replies!
