i just start use kangaroo to analyse a simple structure like below.

can somebody give a hint how to start it? maybe a simple instruction would be very helpful!!

    Hi Frank,

    I agree with Ash's method:

    What you could do is to play around with the resting lengths of your springs (the Gene Pool component grouped in green. Reset the Boolean toggle each time you change the values in Gene Pool). That will enable the load bearing (radial) cable to get some catenary shape.

    Still do not expect this to replace the FEM structural analysis application, as you will not get the forces/stress values in cables, rings, membrane...

      Hi Frank, I would advise to use the analysis of the structure Karamba.

        I put a spoke wheel system and some defination with kangaroo.

        I play with rest length and it works fine for 1-layer variation.

        but for 2-layer variation I got problem, that I couldnt control the verticle-hanging anymore.

         

        does anyone know what could be the problem?
