generative modeling for Rhino
I was wondering if there is a way a wind load could be applied to a free form space frame(truss) in Karamba?
You can either use the mesh-load-component or uniformly distributed beam loads.
'Pos' expects the coordinates of nodes of the structural model where the equivalent loads from the surface loads shall act. Read the manual for details.
The quad you defined consists of points that lie on a line - therefore it has zero area.
Take the full mesh it works.
Thank you Karamba.
So in case I would like to check the wind load on the curtain wall construction of a free form building: I need to use the "Mesh" command from Rhino to convert my surfaces (curtain wall) from Surface to Mesh. And then apply that newly created mesh from Rhino to a parameter "Mesh" in this Grasshopper definition.
At the end I need to apply the supporting points for the curtain wall cladding, as points into the "Point" parameter in this Grasshopper definition.
Or am I wrong?
The mesh for defining the meshload need not contain the points where the surface load is to be transferred to. You could also define a flat mesh that corresponds to the outlines of your building some distance away from it. This makes it easier to have wind blowing from different directions.
The real wind load would have a non-uniform distribution on the building which depends on its shape: pressure at the windward side, suction at the sides and at the leeward side. A uniform distribution however will be a reasonably good approximation.
As I did not understand you, does that "need not" also means that the upper solution is not correct, or just that it can be used, but it is not necessary to be that complicated?
Yes. Try out both solutions and see in what respect they differ.
Thank you for the reply.
I did not understand the one you described.
