LogInVertex Block Descent demonstrates better results than amny other methods.
Researchers from the University of Utah presented Augmented Vertex Block Descent (AVBD), a fast physics-based simulation method in computer graphics. It shows promising results in collision experiments.
The creators introduced a mechanism to handle hard constraints with infinite stiffness without making the simulation unstable and then improved the convergence with different levels of stiffness.

"These changes we introduce allow simulating complex contact scenarios involving rigid bodies with stacking and friction, articulated bodies connected with hard constraints, including joints with limited degrees of freedom, and stiff systems interacting with soft bodies. We present evaluations using a parallel GPU implementation that can deliver real-time performance and stable simulations with low iteration counts for millions of objects interacting via collisions, various joint/attachment constraints, and springs of various stiffness."
The researchers claim their model shows better results than other solutions and can properly maintain contact constraints.

AVBD can be beneficial for complex physical simulations, object interactions, and collision systems. It could also be used in robotics to better simulate movements.
