variable motor strength on a joint depending on its angles

[monsieurpooh]

Hi, I am new to bulletphysics

Based on some research it looks like in order to simulate a human joint, I have to put motors on the joints and do something like SetMaxMotorForce or SetMaxMotorImpulse to limit the strength of the muscle. But in a human body, the muscle of a joint is not constant throughout all the angles. For example, the bicep is much stronger when the arm is curled than when it's fully extended.

So, is there a way to simulate this by setting variable max motor strength, without modifying the bulletphysics source code?

Am I using the wrong library? Is bulletphysics more for real-time gaming and less for precise measurements and simulations?
