increase the processing power of Kangaroo/GH

Dear Daniel, During processing some calculation with kangaroo I noticed that I have problem with my Computer In case of a retractable roof, by dynamic relaxation it works in generally fine with few elements (e.g. only fabric between 2 radial cable).…Continue

Hello Daniel,

I am trying to inflate 4 balloons within a box which itself also inflates. I would like to constraint the balloons inside the box but it is not working. The external surface of the inflatable object collide with the exterior surface of other objects but not the exterior with the interior. Is there something wrong with my definition or there is another way to do it?

Any help on this matter would be really appreciated since it is part of my thesis project!!

Thanks!!!! :)

Hi Daniel,

i'm having an error using KingKong plug-in, this error come from the kangaroo cluster, I think it's for the change of the hinge component in the last update of kangaroo, i'm wondering if someone can share the password for update the cluster?¿ or update the cluster and share again for continue using this nice plug-in?¿

I am trying to create constaint on  an inflattable mesh by using a curve as a spring. I used the mesh collide  component in order to deform the mesh following the curve as a constraint but the mesh doesn't seem to recognize it. I am working on the file that originated from this discussion.
Any help would be appreciated
