I do a dop simulation, an object falls apart. The simulation is done only with one CPU. Is this a limitation of the calculation process or of the apprenticeHD version?

DOPS aren't multi-threaded in general. Only view of algorithms involved by dynamic system can use more then one CPU's core. Collision detection perhaps, maybe something else. This is not an easy task and it's the biggest challenge nowadays I suppose - to make various simulation process more scalable.

As much as I know, there is no publicly available software that can do this in reasonable extend.


cheers,

No it isn't. Not all areas in DOPs are multithreaded. Even in the areas that are multithreaded, it won't use multiple threads unless it thinks it will give a speed advantage.
