Hi! Do you have a link for the project, or perhaps some images showing the exact application?
From the description alone, I’m not sure if I understand fully what you are trying to achieve, but here is how the rotating zone formulation works for the same axis of rotation, based on different origins:
- If the origin is centralized at the propeller, then the propeller rotates as we would expect:
- If we maintain the same axis, but tweak the origin, then the rotating zone behaves very differently:
Does this answer your question?
Cheers
