Btw I have managed to eliminate all differences in the inputs between the Kangaroo def and the structural program. The results are pretty much the same, and any differences I have managed to find were totaly negligable. Thank you very much for all that help these few days. You have made my life a lot easier.
I will wait for the reaction forces definition, because I just can´t get it to do it myself.
But this example you gave me here reised another interesting question. Since it is possible to materialize cables with Kangaroo, could I do the same for PVC membranes or ETFE cushions? I have a very specific kind of load which I need to iterate great many times to get a valid result. If I can do the same kind of materialization in real units with Kangaroo, I have the rest of the definition ready.
I must say Kangaroo proves to be invaluable, I have a bit of trouble understanding all but with your help and examples I gain ground quickly. Thank you again for all this.
