Real-Time Physics Simulation Forum

I'd like to model a small vibrational motor (like a pager motor). Typically these work by spinning an off-center mass around an axis. Any advice on how to go about doing this in Bullet Physics?

To complicate matters, I'd like the motor to be attached to a soft-body, and to not collide with anything.

thanks!

I assume you're trying to do FEM like calculations? If so, you should check out some of the FEM experiments on bullet's github.

In general though, consider if you need to simulate the spin or can actually calculate it directly, direct calculation with torque and forces might make soft body simulation more stable.
