View Full Version : Using particles/smoke to "streamline"

09 September 2010, 10:20 PM
We've all seen it. A glass box, smoke coming out one end and a car in the middle. I have the car, I have an emitter, and I have a fan, as illustrated below.

Now, I am trying to simulate said car lab, but am having difficulty. The car and the road are both Passive rigid bodies. Any ideas, or am I going to have to insert the smoke and use that?

how would I do it? make a fluidic volume container?

i know what I'm asking is probably obvious... and i apologize in advance.

Read the notes section in the Attribute Editor for the windTunnelShape node.

you need to dial up your substeps. Depending on how fast your particles are travelling they may have intersected the surface in between frames.
But as thinkr has mentioned the windtunnel preset has a nice expression for setting in velocity to normalize velocities through a fluid container, perfect for this type of effect.
