Barcelona Wind Simulation for 2012.07.27

Testing out the upcoming Field components for Grasshopper 090002. Here I use wind direction and speed coming from a Weather Underground query for 2012.07.27. Data is accessed by a request in Grasshopper and then treated to interpolate between the readings. The point fields are just placed randomly to test this out.

nice work..I like it..thanks

thx Ángel...its obviously not a cfd...just fun with forces as you mention!

Mmm...the problem is that this kind of analysis is not the same than aerodynamics analysis because the field doesn't generate turbulences behind objects (charges), doesn't take care about fluid properties (temperature, density...),for the moment...Is only a nice little play with physical charges.

I've posted a definition here with some basics configurations to play with: http://www.grasshopper3d.com/forum/topics/field-componets-definition

I could share the definition, but you would not be able to run it until the release of 090002.  Trust me, when that comes out, these sorts of things will be trivial.

Great job Luis !! I have been trying to simulate wind but all I could do was this

This is amazing you could extract the data & transform them into vectors.

However I hope you could share the definition with us ? :)

Don't thank me!  I just had fun with it... This is all David's doing.

Comment by Daniel Kautz on July 29, 2012 at 3:52pm

Very interesting, thank you Luis + David.

Comment by Luis Fraguada on July 29, 2012 at 3:44pm

From what I can tell David has implemented Euler, RK2, RK3, and RK4 solvers.

Comment by Daniel Kautz on July 29, 2012 at 3:39pm

How is the flow simulation implemented? Is it smooth/laminar flow or have you included navier stokes algorithms for turbulence?

I will very much look forward to playing with the field components!

Interesting
