Hello formers
I have been doing an airfoil pitching case in OpenFOAM and I was able to do the pitching from angle 0 to -1. But I have to do a pitching case such that the airfoil starts from 0 to -1 and then to +1 and so on in an oscillatory form.

My dynamicMeshDict for 0 to -1 is given below

dynamicFvMesh      dynamicMotionSolverFvMesh;

motionSolverLibs ("libsixDoFRigidBodyMotion.so");

solver            sixDoFRigidBodyMotion;

        yLine
        {

            direction                 (0 1 0);
        }

        zAxis
        {
            sixDoFRigidBodyMotionConstraint axis;
            axis                (0 0 1);
        }
    }

    {
        verticalSpring
        {

            refAttachmentPt (0.25 0 0);
            stiffness            4000;
            damping             2;
            restLength          0;
        }

        axialSpring
        {
            sixDoFRigidBodyMotionRestraint linearAxialAngularSpring;

            axis                 (0 0 1);
            stiffness          700;

            referenceOrientation $orientation;
        }
    }
}

Can anybody tell me how I can generate an oscillatory airfoil pitching in OpenFOAM.
The solver I am using is rhoPimpleDyMFoam.
