If you are using a computer that has more than one core, it is advantageous to turn on the parallel processing feature of FLUENT when the mesh gets large. This feature will divide the solution domain amongst the number of cores that you specify. The maximum number of cores that you can specify is 4 for the standard FLUENT package. The Swanson Lab at Cornell University has dual core machines. In order If you want to use both cores, set Processing Options to Parallel (Local Machine) and set the Number of Processes to 2. These selections are shown below. For this problem, you might not get much speedup by using both cores. So you could also leave it at the default of "Serial" which will use one core.



If you have more cores set Number of Processes to the number of cores you have ( 4 is the limit). Now, when you run your calculations in FLUENT you will have more than one core working for you, which will significantly reduce your computation time. Lastly, click OK.
