Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Simulate physics for industrial mechanisms

I'm currently trying to find a way to physically simulate mechanisms for industrial purposes (those mechanisms are modeled by engineers). Those mechanisms have a lot of constraints and can be composed of tiny pieces.

Here is an example of simple mechanism: alt text

I tried to use PhysicalConstraint to simulate this simple mechanism but there are lots of instabilities which completely broke up the whole thing (the physics engine tries to solve all those constraints but the simulation seems to produce more and more instability which leads to more and more tremors until everything fall appart).

I tried to solve those instabilities by several ways (scale the whole mechanism, set the same mass to all pieces, for a given constraint tweak which piece simulates the physics, etc,), but it seems there is no way to properly simulates it. It seems that internal collisions make the simulation unstable.

Do you think that I should code my own simulation or there is another way to solve my problem (if I have to code it I don't know what to do because everything I need is physics and I don't think that I will do a better job than PhysiX) ?
