NVIDIA Omniverse™ provides advanced simulation capabilities for adding true-to-reality physics to scene compositions. The tools are made available through Omniverse Kit extensions.

| Extension | Description |
| --- | --- |
| ![Image 1: physics_core_img](https://docs.omniverse.nvidia.com/extensions/latest/_images/ext_sim_overview-physics_core_extension.png) [Physics Core](https://docs.omniverse.nvidia.com/kit/docs/omni_physics/latest/index.html "(in Omni Physics)") | Powered by the NVIDIA PhysX SDK, you can add rigid-body dynamics to building blocks and topple them over; create ragdolls or simulate walking robots using articulations; build complex mechanisms using joints; or pour a jar of gummy bears into your scene using deformable-body simulation. |
| ![Image 2: clash_detection_img](https://docs.omniverse.nvidia.com/extensions/latest/_images/ext_sim_overview-clash_detection_extension.png) [Clash Detection](https://docs.omniverse.nvidia.com/extensions/latest/ext_clash-detection.html#clashdetection) | Find and inspect clashes between meshes in large stages. |
| ![Image 3: flow_img](https://docs.omniverse.nvidia.com/extensions/latest/_images/ext_sim_overview-flow_extension.png) [Fluid Dynamics](https://docs.omniverse.nvidia.com/extensions/latest/ext_fluid-dynamics.html#flow) | Add fire and smoke to your scene with Omniverse™ Flow, an Eulerian fluid simulation tool. |
