I try to use overset with openfoam for a turbine type Darrieus.I transformed the case of K S S Satya Sasank "aerofoilC" which has a single overset with the 3 blades included. I created 4 overset with 1 blade per overset. in the log of overPimpleDyMFoam, I get this message.


--> FOAM Warning :
From Foam::tmp<Foam:imensionedField<double, Foam::volMesh> > Foam::RASModels::kOmegaSSTLM<BasicTurbulenceModel> ::ReThetat0(const Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>::Internal&, const Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>::Internal&, const Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>::Internal&) const [with BasicTurbulenceModel = Foam::IncompressibleTurbulenceModel<Foam::transpor tModel>; Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>::Internal = Foam:imensionedField<double, Foam::volMesh>]
in file ../turbulenceModels/lnInclude/kOmegaSSTLM.C at line 305
Number of lambda iterations exceeds maxLambdaIter(10)

can you solve my error? thank you


the software used to create the NACA profile is openscad. If you don't have openscad installed on your computer, here are the stl naca profiles you need to incorporate into the triSurface directories, and delete the ./render.sh command from the Allrun.pre file in each directory.
