Hello !

I'm using OpenFoam-9 to evaluate the power generated by wind turbines modelled with the Actuation Disk model and the Rotor Disk model. I'm working in stationnary state using simpleFoam. I defined those model within the topoSetDict dictionary as cellZoneSet and i would like to compute axial and tangential forces and moments acting on those cellZoneSet.

I saw that solvers in OpenFoam offer a postProcess utility with function objects such as forcesIncompressible which seems to be the best thing to use in my problem. However, using forcesIncompressible in the controlDict dictionary requires a list of patches and Actuation Disk or Rotor Disk (cellZoneSet) seem not to be patches, or at least I did not find which type of patches. I saw that patches were defined in polyMesh/boundary but then i still don't know which is the type of patch to choose.

Thus, is there a way to use the postProcess utility and forcesIncompressible function for the Actuation Disk and the Rotor Disk and, if yes, how to do it properly ? Other use, could someone give me a hint of how to get compute forces for the Actuation and Rotor Disk model in OpenFoam ?

If any of you have suggestions, i would be very grateful for the help.

Kind regards,
