===Simulation===
[[File: Cloth on suzanne.ogv|alt= A cloth simulation made in Blender|thumb|Cloth simulation]]Blender can be used to simulate smoke, rain, dust, cloth, fluids, hair, and [[Rigid body dynamics|rigid bodies]].<ref>{{cite web|title=Introduction to Physics Simulation — Blender Reference Manual|url=https://www.blender.org/manual/physics/introduction.html#introduction-to-physics-simulation|website=www.blender.org|access-date=2015-12-02}}</ref>

====Fluid simulation====
[[File:Physics-Fluid-Simulation-Blender.gif|thumb|Physics fluid simulation]]The [[Fluid simulation|fluid simulator]] can be used for simulating liquids, like water being poured into a cup.<ref>{{cite web|title=Create a Realistic Water Simulation – Blender Guru|url=http://www.blenderguru.com/tutorials/create-a-realistic-water-simulation/|website=Blender Guru|date=9 November 2011 |access-date=2015-12-02}}</ref> It uses [[Lattice Boltzmann methods]] (LBM) to simulate fluids and allows for plenty of adjustment of particles and resolution. The particle physics fluid simulation creates particles that follow the [[smoothed-particle hydrodynamics]] method.<ref>{{cite web|title=Fluid Physics — Blender Reference Manual|url=https://www.blender.org/manual/physics/particles/physics/fluid.html|website=www.blender.org|url-status=dead|archive-url=https://web.archive.org/web/20151208070913/https://www.blender.org/manual/physics/particles/physics/fluid.html|archive-date=2015-12-08|access-date=2015-12-02}}</ref>

Blender has simulation tools for [[soft-body dynamics]], including mesh [[collision detection]], LBM [[fluid dynamic]]s, smoke simulation, [[Bullet (software)|Bullet]] rigid-body dynamics, an ocean generator with waves, a particle system that includes support for particle-based hair, and real-time control during physics simulation and rendering.

In Blender 2.82, a new fluid simulation system called Mantaflow was added, replacing the old FLIP system.<ref>{{cite web|title=Reference/Release Notes/2.82 - Blender Developer Wiki|url=https://wiki.blender.org/wiki/Reference/Release_Notes/2.82|access-date=2020-06-10|website=wiki.blender.org}}</ref> In Blender 2.92, another fluid simulation system called APIC, which builds on Mantaflow,{{citation needed|date=October 2021}} was added. Vortices and more stable calculations are improved from the FLIP system.

====Cloth Simulation====
Cloth simulation is done by simulating vertices with a rigid body simulation. If done on a 3D mesh, it will produce similar effects as the soft body simulation.
