dynamica 101
Posted: Sat Jul 17, 2010 12:50 am
I have run some test using dynamica but there are certain basic things I would like someone to help me grasp. I've looked in the forums and downloaded some test scenes which are primarily cubes or donuts, etc. I am assessing how far I can take the tool for some production we are doing.
I am using the dynamica 2.76 plugin in Maya 2010 64 xp 64.
Here's one question: Why, when I create active bodies (hull or mesh methods) upon collision they self attract?
(See first attachment)
Here's another one: I understand that most solvers that have intersecting geometry start the sim "exploding"... some allow you to control the collision thickness, and some even allow you to start the sim "sitting" on each other... I don't quite get how Dynamica handles this. The second file I am attaching has a cube broken into pieces that touch each other, there's a slight ejection between the pieces ... is .1 the minimum distance I need in order to avoid this ejection? What would it be the procedure if I design say, a building or an object that needs to break from a whole to pieces? Someone seems to be able to do it using Dynamica (see "B breaking" link http://www.youtube.com/watch?v=k4tbOW5b ... re=related), for test file, see attached second file. I would love if someone would post such a file in the forum or explain how to get there.
Another questions is in regards to the bounciness of objects... How do I control that attribute? (See third file).
Any one who could shed some light or point me in the right direction, I'd appreciate it. Some more sample files or tutorials would be great. I am impressed at the speed at which dynamica resolves sims.
Thanks in advance, Jim.
