I’m testing a basic simulation using Unreal Engine’s chaos physics engine.
I’ve made a blueprint to apply torque, measure angular velocity and acceleration, and calculate mass moment of inertia.
In Case 1, where there’s only one geometry, Unreal Engine’s results matched my direct calculations. However, Case 2, involving two connected geometries with a physics constraint, has issues.
(1) Despite turning off gravity and applying constant torque, angular velocity didn’t consistently increase.
(2) Also, the system tends to stabilize at angular velocities below the maximum.
My goal is to find the mass moment of inertia by applying torque to connected geometries, aiming for steady angular acceleration while eliminating gravity’s effect.
How can I accurately perform physics simulation of two geometries connected by physics constraints?
Thank you for your assistance with this question
