I have been playing around with Flow Simulation on my new work PC, and have noticed that the solver does not utilize much of the resources I seem to have available. I'm running an Intel 3960X six-core processor with 32GB of memory with Windows 7 x64 and SW2011/SP5.0, and during the solving process I only see a maximum of 20% cpu utilization. Memory usage hovers around 3.5 to 4.0 GB (the model is not very large so this is probably not an issue). From watching the resource monitor, it doesn't seem like there is any large amount of hard disk activity going on either. I've tried changing the priority for SW to high with no luck.
I have turned off hyperthreading, and was told it would actually slow down the calculations. Are there any settings I should change that would let Flow Sim use more of the PC? I would have expected the flow solver to eat up as much cpu power as was available, which is why I went with a fast six-core processor in the first place.
