Slow simulation

[arizawilmer]

I am running a simple example of cfd in cfd 2015 trial.

I am passing a fluid from one tank to other tank. . I have a amd  8350 with 16 gb of ram , ddr5 of 1gb and a ssd but the simulation time is faster in my latop that in the desktop .

Any clue what can be the reason of the slow simulation.

The relative performance between the laptop and desktop machines may have to do with the problem size.  Could be that if the problem element count is not too large, then the resources of the laptop are better matched to the problem being solved.  For example if your laptop has 2 or 4 cores and you have a 12 or 16 core desktop, the laptop may do a better job of running a problem with a moderate or small element count.

Checking the PC use i only using in the desktop a 1% of pc and a 20% of ram. that is to small compare to my latop with the same model. My laptop is a I7 2nd generation with 8 gb ram and 1 gb ddr3 of video.

When you say, "Checking the PC use i only using in the desktop a 1% of pc and a 20% of ram", I am assuming that the task manager is showing 1% CPU usage and 20% Memory.  1% CPU usage does not seem right.  I have a 12 core Nehalem and I typically see ~ 60% CPU usage ( ~ 8 / 12 cores ),  Do you have a cfz file that you could attach?  What is the element count?
