Hello Everyone,

I am trying to set up a case in OpenFOAM with two non-coaxial rotors, see picture rotors.png. I have tried with pimpleDyMFoam using the following setting in dynamicMeshDict:
Code:
dynamicFvMesh   solidBodyMotionFvMesh;

motionSolverLibs ( "libfvMotionSolvers.so" );

solidBodyMotionFvMeshCoeffs
{
    cellZone        innerCylinderSmall1; // for rotor 1

    solidBodyMotionFunction  rotatingMotion;
    rotatingMotionCoeffs
    {
        origin      (0 0 0);
        axis        (0 1 0);
        omega       40; // rad/s
    }

    cellZone        innerCylinderSmall2; // for rotor 2

    solidBodyMotionFunction  rotatingMotion;
    rotatingMotionCoeffs
    {
        origin      (0.5 0 0);
        axis        (0 1 0);
        omega       40; // rad/s
    }

}
However, only the second rotor rotates in the simulation, see picture rotors02.png. I believe that pimpleDyMFoam might not allow multiple non-coaxial rotating zones. Do you have any suggestion?
Thank you very much for your help!
