"Hi Roberto, The point load you define goes directly into the support. Use a pre-strain load to create axial forces (see attached definition). Best, Clemens"

Roberto replied to Roberto's discussion Cable net w/ Karamba and Kangaroo in the group Karamba
"The only doubt I still have is if it's correct how I am applying the axial loads on the cables. Because from the "Results" I am seeing that everything is 0 and it could be since that the cables are in equilibrium but trying to apply…"

"Hi Roberto, I just looked at the definition quickly and noticed that you have separate models for each cable. You need to make sure to combine everything into one model so that Karamba calculates it as one system. Please see the definition I…"

"Hi Clemens, I tried to create the same cable net in the final configuration on Karamba abandoning, at the moment, the idea of doing the form finding and the finite element analysis together. I am having some difficulties with the "Model"…"

"Hi Clemens, thank you for your reply. Sorry I forgot to attach the rhino file. Please, find attached it now. I tried to put the Show component into the solver but nothing happens.. maybe I am wrong with it. My problem is that now that I found the…"

karamba replied to Roberto's discussion Cable net w/ Karamba and Kangaroo in the group Karamba
"Hi Roberto, your definition does not contain a geometry - I think you forgot to internalize it. I am not a Kangaroo expert, but in Kangaroo2 one can feed geometry via the 'Show'-component into the solver which then gets co-deformed (see…"

"Nothing has changed in the way multiple inputs are connected - it still works by holding shift while connecting the wires. It looks like the anchor points and the lines just got moved separately, so they are no longer connected. Make sure the anchor…"

Cable net w/ Karamba and Kangaroo

Hi Guys, I am working on a project about cable nets on Kangaroo. I found the form of the net with Kangaroo and now I would like to do a FEA with Karamba. Is it possible?I am having some difficulties because it's like if on Karamba my beams (which are trusses) are recognized only in their initial form and not in the one I found with Kangaroo. How can I do a FEA on the final form I found? I have also another question about the supports. To assemble the model I had to create the supports but I…See More

"Hi Daniel,  I used your gh file and I have the same results of my code made on Matlab! Fantastic. Now what I am asking to is if something has been changed on kangaroo in a new release since you created this gh file. I noticed that on the…"

"Here's a simple example with 4 cables with prescribed tensions. For a presentation of Kangaroo more from an structural engineer's perspective, you may also find useful Cecilie Brandt-Olsen's work…"

"Hi Roberto, "if it is possible to do form finding with kangaroo" - Yes, indeed this is the reason it was created!  "what are the methods on which it is based" - as Shezhad correctly says, the Kangaroo solver uses dynamic…"
