I would like to move an object inside a fluid domain, which has no velocity at inlet. I am trying to use the dynamic mesh, but it seems there are very few tutorials or notes that are understable for me. And I have a few questions:

1. After I created dynamicMeshDict in constant folder and defined the motion in the dictionary, is there any other dictionary or setup required? I saw some tutorials use toposet, but I have no idea what is that and if that is needed in my case.

2. Can the axisRotationMotion define a rotation axis that does not lies inside the rotating object? What I mean is that I would like to do something like a car driving along a circular path, and this can be done by rotating the car along an axis that passes through the center of the circular path.

3. If possible, could anyone list the basic steps required for a simple rotational motiom, in case that I already have the setting without motion?

Thanks a lot Foamers!!
