Hello,

I am working on a Vertical Axis Wind Turbine (VAWT). I want to do a dynamic simulation with pimpleDyMFoam. My problem is to define the interface between the static part and the rotating part. The rotating part is a cylinder around the wind turbine. I defined the faces of the cylinder as a wall with the tool "Named selections", called cylinder.

I don't know how to define the rotating zone after I converted the mesh in OpenFOAM. I have the AMI1 from the cylinder when I run createPatch but I can't create AMI2 (this boundary condition is empty).

I think I need to add this but I don't know where to write it and if it's correct :

AMI
{
faceType          boundary;
cellZone           rotatingZone;
faceZone          rotatingZone;
cellZoneInside  inside;
}

I read a lot of threads about this subject but I didn't find an answer to my problem.

Thank you for your answers,
Jacques
