Hi All,
I am trying to simulate the solid body motion in an incompressible fluid using pimpleDyMFoam. The solid body is free to rotate at a point around the z axis for the following constraints and no linear displacement is allowed. In my simulation, the body is starting to rotate then the simulation crashes due to the severe rotation. I want the solid body to stop when the total rotation angel exceeds a certain value as if the solid body is stopped by a stopper. Is it possible to limit the maximum rotation angel during the simulation?
Thanks in advance..

sixDoFRigidBodyMotionConstraint point;
centreOfRotation (0.52 0.043 0);
}

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