Using the Functions Utility I am trying to calculate total mass flow at internal faceZones using interFoam solver. But while running the case I got the error. The same case was running in OpenFOAM 2.1.0 version but using openFOAM 2.3.0 I got this error. is there any difference between these two versions ? How to deal with internal faceZones in version 2.3.0 for post Processing ?

In controlDict, I am using the functions utility.

}

Hi Jimmy,

did you solve your problem? I got a similar one and don't know how how to solve it

Your issue is likely because alpha.water is a volume field, but you're using surfaceRegion. It is expecting a surface field, instead of a volume field. Maybe try to interpolate the field onto a surface field?

I don't think that volume field is the issue. As in the original post, it has been indicated that the same case was successfully run with OF2.1.
