Hello,I'm working in a .gha library that tranforms GH data into custom data (from custom classes). Then I have a final component that takes all the data and do some operations (it's a form-finding…Continue

PointLoads to Vector3d

Hello,I'm trying to assign some accidental loads as mass to Natural Vibration analysis, I wrote a short script trying to retreive the PointLoads from the Disassemble Mesh Load component and return the load vectors from it:private void RunScript(object x, object y, ref object A, ref object B) {Karamba.Loads.Mesh_PointLoad load = (Karamba.Loads.Mesh_PointLoad) x; A = load.position; B = load.force;}However, I got this warning: 1. [A]Karamba.Loads.Mesh_PointLoad cannot be converted in…See More

"Hello Silvia, For deck weight you should model a mesh of it and add a Mesh Load component including the nodes you want to consider (See Karamba manual for details, also in the previous comments I helped ma qingsong with a similar problem). For…"

"Hello Qisong, I will answer here to avoid over posting in the comments section. See attached a example file of what you can do. Basicaly you need to fit the steel plate with the upper part of the waffle for a correct analysis, the way I see to…"

"Hello Qisong, See attached the changes I made. To parametrize the thickness of the plate you just need to multiply its material density with the thickness (going from kN/m³ to kN/m², or just from volume to surface load). ma20170129.gh"

"In order to use "sig_max"... you have to switch to Karamba 1.2.0. For the cross section optimization according to EC3 Karamba uses a buckling length for each beam-element which is either user defined via the ModifyBeam-component or…"

Retrieving Karam Information (Script)

Hello everyone,I'm trying to work on penalty functions to set up structural constraints in Galapagos optimization.To do so, I would like to know how to acess the follow itens in C# while scripting in Karamba:-Beams axial stress by node (or utilization) list-Shells Von-Mises stress by node (or utilization) list-Nodal displacements list-Element buckling informationThanks in Regard,Márcio SartorelliSee More

"No, both languages eventually call the Guid type constructor which is implemented only once. There's no special .NET flavour for C# and VB. "

Fala Marcio, Tudo bem?

Vim ver justamente a dúvida sobre mexer diretamente na matriz de rigidez do karamba, vi o seu post e notei que você é também é da poli. To mexendo um pouco com MEF no grasshopper, quero fazer análises não linear de construção sequenciada, mas quando arranjo tempo livre hehe, devagar e sempre. 


vamos trocar uma ideia aí, vê se não nos ajudamos.

Abraços,

Bruno
