Creating fluid animations with Blender’s fluid simulator

When animating, some actions are difficult or very time consuming to get right, such as explosions, fire, hair, cloth, and physics-related actions like moving fluids and bouncing objects. One solution to get these actions to look right is to let the computer do the work and create a simulation of that action. You use variables like gravity and mass to define the environment, and the computer calculates how the objects in the scene behave based on the values you set. Using the computer is a great way to get nearly accurate motion without the need to key everything by hand.

That said, don’t make the mistake of thinking simulations always give you a huge time savings in animation. This assumption isn’t necessarily true, because some highly detailed simulations can take hours, or even days, to complete. Instead, think of simulations as a way to more reliably ...
