Wind analysis by grasshopper

Hi all,

I am currently designing a hotel and trying to analysis wind by grasshopper. But don't know how to it.

Please help me out. thanks.

BTW: Patriarch of modernism (but is/was this a good thing?) Louis Henry Sullivan stated quite clearly: Form follows function. Adopting the other way is the path to oblivion (sooner or later).

Back to gone with the wind topic: since this is utterly Academic the main issue here is to oversimplify LBS (in real life: a collection of columns/beams/slabs/X members + tube frame rigid members (shafts/elevators/cats/dogs)). Reason is that if we use the real "solids" (turned into meshes) as the "node" pool for the hinges required ... only HAL 9000 could solve it in "real-time" (for instance an E5 Xeon 1630 v3 takes ... several minutes). And this is ... er ... challenging I must say. This is a typical case where "simplifying" means "stupidity" almost instantly.

Spam on:

where's my collection of "bend-a-truss-that-looks-like-a-tower" K1 demo defs? Is in this workstation or in another? (blame Alzheimer).

Spam off.

More soon.

Going to node 0 (nesting in answers is not the forte of this noble forum).

After testing several approaches via K1/K2 (all stupid: a lot of computational time for what? GH is not a structural analysis app NOR Rhino is a BIM thingy) I've decided to switch direction entirely: forget "bending" and concentrate on ways to have "some direct" (add some "" more) clue about wind forces.

V1 is a bit "basic" (no suction, not to mention the MIA remap force vector values thingy) : V2 does a lot of things more (and the test case is far more ... er ... "challenging": a twisted ultra ugly tower, what else? he he).

BTW: other than LBS "bending" ( pro-stuff for proper FEA SA apps: forget it) the most interesting thing is the air infiltration and water penetration min/max "suggested by building codes" values (a bit "elastic" in several countries) that ... are easily blown away if ... wind blows, that is. As Kim said: don't invest on cheapo curtain walls.
