Cenk Posted November 8, 2012 Share Posted November 8, 2012 Hi everyone, I'm having this weird problem with RBD system. I'm trying to create a RBD system for my chain network. Used pin cons. to pull my system but as I pull it down RBD system doesn't want to recognize last piece of my chain(the one connected to pin cons.) and breaks the whole system. I tried different scales + sub stepping and things like that but no successful result in the end. Any help would be awesome! chain_system_005.hipnc Quote Link to comment Share on other sites More sharing options...
rafaelfs Posted November 9, 2012 Share Posted November 9, 2012 What was your intention in this file? There isn't anything wrong with the setup, but I'm not sure if it ultimately will accomplish what you want to do... Right off the bat, you won't be able to run that chain through the wheels, not in 2012 I don't think... Please, take no offense, I mean in practical terms the number of collisions involved alone is enough to keep your machine thinking for a long time. You might be able to do it with wire dynamics, but I'd suggest you optimize your simulation geometry a lot before trying to make it work.

Cenk Posted November 9, 2012 Author Share Posted November 9, 2012 Thanks for your time. My sim time feels ok and I actually don't have any problem with my RBD until I pull my last piece with a rbd pin cons, Even though my collision geo is good, it doesn't want to collide with the system after a certain point of strees or force. It feels like it's something to do with my density values. But I couldn't come up with any proper result. That's why I can't understand it passes through instead of colliding. I'm still looking for a solution for that problem. Quote Link to comment Share on other sites More sharing options...
Fabiano Berlim Posted November 12, 2012 Share Posted November 12, 2012 The constrain is not providing the vel attribute to the "master_front_chain_holder" object. So you need to feed that yourself. Quote Link to comment Share on other sites More sharing options...
