Model instability

[RickYang1]

I am using the Sofa Unity tool from InfiniyTech3D. I have created a model of the capsule, which is a very thin tetrahedral mesh. After cutting in Unity, I interact with the model using the mouse. Even when I stop interacting, the model still maintains motion. Is there any way to make the model stable as soon as possible?
The effect is shown in the video below. I ended the mouse interaction (pulling the model) in the 9th second, but my model kept shaking.

I have tried the following methods:

1. Increase rayleighStiffness, rayleighMass, and damping;
2. Reduced time step size;
3. Modified the corresponding way of ContactManager: from PenalityContactForceField to FrictionContactConstraint, and adjusted the contactFriction and contactStiffness of CollisionModel.
   But I haven't solved my problem very well. May I ask which direction should I try again?
   Here are my scene files:

   Looking forward to your reply, best wishes!

Hi @1044351427

I am unsure to understand understand what is not desired in your simulation ("Even when I stop interacting, the model still maintains motion. Is there any way to make the model stable as soon as possible?"). You object being deformable, it has itts own dynamics and it moves accordingly.
Did you properly define the mechanical properties of your object?
I get the feeling that either there is mis-defined numerical settings or that you are looking for a very damped behavior.
