Solvers & Multithreading

[user_deleted]

Hello Everybody,

I am encountering a lot pf problems with rgid bodies solvers because i have to do a lot of coins that come from up and stack on each other. The solver , even the Mid Point Solver it's taking too slow to execute all of the simulation, and it's very frustrating because i have a 2 X dual core Opetron X64 (total 4 procs) and maya it's using only one.Why? What can i do to make the soler to use all of my 4 procs? It's Urgent because i heve to finish this project in abouth 2 days!!!

afaik dynamics (at least till maya7) does not support multiple CPUs.
one thing You can do to speed up sim is to turn all fallen coins to passive, or even sim in portions, just bake one sim after each other.. afterwards You can add some small nuances by manual animation.
Yes, and better use some primitive (e.g. hex- or octagonal cylinder as rigid body) for each coin - this will speed up significantly.

I have solved my problem in 2 ways. one way , i use the stand in attribute of the rigid bodies, and it speed up the whole things significantly.Of couse i have bake the simulation in portions, and this was my final decision. Now, i have experimented other stuff , by writing an expression wich turned each active rigid body after colision in an passive r b. of course this was tricky, but it worked. I choose the first one, because was more accurate, ...i wanteh that my coins to folow with some initial spin. By the way i have maya 7 & 8 and the simulation was the same. I mean THE SAME...So, thank you and see you some other time.
