I want to make a model that various seat parameters (e.g., seat-pan and backrest inclinations) and the external force in the environment (e.g., accelerator pedal spring stiffness and steering wheel torque) can adjust. But always told me that Model Warning: Study ‘Main.Study’ contains too few kinematic constraints to be kinematically determinate. The vision is 5.3.0

Dear wenhao Li,

it is very difficult for me to recreate what you changed from your original model. Can you start again and try to run it after changing every step.

the error message means, that something is not being driven in your model.
