Ok, thank you for information! I have to think about it for making decision.
My task is to simulate rocks with destruction possibility. Actually I have started my own program for that, but it is 2D model. So know I should migrate to 3D, using my program or something another. What is your opinion, is it really difficult to learn YADE for adding new modules?
