Ira Krakow’s Basic Fluid Simulation Blender Tutorial

By Ira Krakow

The purpose of this video is to show how the objects in Blender’s fluid simulator work. We’ll look at domains, obstacles, inflow, outflow, and of course fluid objects. Blender’s fluid simulator at first seems very challenging. However, if you think about how fluids behave in real life – think of water pouring out of a faucet into a sink or a bathtub, the fluid simulator starts to become more logical. In this tutorial we’re going to focus on the objects in Blender’s fluid simulation.

Let’s start with the most basic fluid simulation. At a minimum, the fluid simulator needs two things: a fluid, which can be free flowing like a waterfall or muddy like water in a pond; and a domain, which is an area in which the fluid lives. Be warned. This doesn’t look exactly like water dripping from a faucet, but it does look like some icky gook falling down in a fluid like manner.
