Default Starting Toposet Rotor Grid at an Angle

Hi,

So I have a grid that consists of a rotor toposet inside of a stator. I would like to know if I can specify an angle for the rotor grid to start at, (right now it starts horizontally). I have tried varying the origin and amplitude in dynamicMeshDict but haven't been able to get it to work.

Is there an easy way to set the grid to start at a specified angle rather than having to figure out how to redraw it?

Also, if anyone knows how to specify an alpha value for angular acceleration here instead of a constant angular velocity, that would also help!
