But you can also see the spiraling death vortex turbulence area that I suspected would form in the recessed area of the tower. With that one button push I go from 15,626 2d cells to 1,515,625 3d cells being analyzed. Notice how most of the area around the model is not very differentiated? This is because my computer is just beginning to process all the voxels. For instance, on my 8 core machine, I popped on 3d analysis, waited 4 minutes, and had this This is where you will jump from “real time” to something more intensive. To take this into account, you need to check the 3D Analysis button. But with my corkscrewing geometry, I’m pretty sure that I’m getting a vigorous 3 dimensional churn, probably a big rush of wind coming up from the innocent victim trap plaza. Now, this is fine, it gives you a good starting point to understanding your model. This is what I get after only a few seconds using the default settings on my model. The default behavior is to use “2d analysis”, which is very fast to calculate, but only takes into consideration the winds and geometry of a flat plane. This takes computing power, so you’ll want to stop analyzing and start visualizing. Pause your analysis before exploring it: Moving around the data slice and using other methods of visualizing the analysis is where the fun comes in.Let the analysis run for a while before really looking at it: crunching voxels is hard work, and you wanted to get some coffee anyway.Use 3d analysis for more robust results: 2d is fast, but only takes a small area of your model into consideration.Now, a couple other things I like to consider when jumping in on this tool: Mwah-hahahaha!įor basics on how to use the functionality, check out this link.

I think my building is going to suck pedestrians off the sidewalk.

The Wind Tunnel analysis available in Vasari 2.1 is mesmerizing.
