*** OpenFoam 9 / Ubuntu ***

Hi

I'm having troubles with an AMI simulation (a simple FAN in a fluid). I run a parallel PimpleFoam and i obtain this message :

--> FOAM FATAL IO ERROR: 
Cannot find patchField entry for AMI

file: /home/nico/OpenFOAM/nico-9/run/CE-MOD1-AMI-V1/0/T/boundaryField from line 25 to line 55.

    From function void Foam::GeometricField<Type, PatchField, GeoMesh>::Boundary::readField(const Foam::DimensionedField<TypeR, GeoMesh>&, const Foam::dictionary&) [with Type = double; PatchField = Foam::fvPatchField; GeoMesh = Foam::volMesh]
    in file /home/ubuntu/OpenFOAM/OpenFOAM-9/src/OpenFOAM/lnInclude/GeometricBoundaryField.C at line 184.

FOAM exiting

My Mesh is Ok (I use SNAPPY and i check the quality with checkMesh and the different patch on Paraview), and my AMI patches are in the T file as below :

I really don't understand if someone can help, after the patchfield entry error for AMI i have the following error for the 16 processors, but i assume it's the result of the first error :

Thanks a lot

Hi


I found my pb if it can help somebody :


I see in the mesh log that my baffleFaces did not convert faces into boundary faces in patches.


In the snappyhexmesh i had a faceType boundary which block the patches creation. I suppress the line and the solver run, with another problems ...

refinementSurfaces
     {
         AMI
         {
             level (2 2); // Note: better: levels 3 3
             faceType boundary;
             cellZone rotatingZone;
             faceZone rotatingZone;
             cellZoneInside inside;
         }
         fan{ level (2 4);} // Note: better: levels 3 3
         outlet{ level (0 0);}
         inlet{ level (0 0);}
         walls{ level (1 1);}
     }

Best regards,
