Quick Wind Tunnel

Usually you’d find pyro setups behind all kinds of explosions, fires and sometimes fireworks, but how about something more calm? Something like a wind tunnel used to evaluate the aerodynamic properties of cars, trains and planes? (Please do not use this setup to evaluate any aerodynamic properties, it’s a visual setup, not necessarily a scientifically accurate one.)

In this tutorial we’ll go through the steps necessary to build a wind tunnel using Houdini’s pyro toolset. We’ll talk about emitting smoke, building a virtual fan to blow the somke over our test surface and setting up our simulation parameters.

This is Stefan Sietzen’s original tutorial which I’m referencing in the video.

    06:25 – How can you do negative axis for the velocity? Say -Y or -Z?

      Hi Aki,

      simply set the desired value in the “Default Value” fields of the pyro source node.

      Cheers, Mo
