Because people still refer to this post, I will note that Marshall’s results were obtained prior to TurbSim v1.50. Memory requirements in v1.50 were significantly reduced: TurbSim can now generate grids of 75 x 75 points (630 seconds at 20 Hz) using about 1.8 GB of RAM, which will run on a 32-bit computer. A grid that size will take a long time to generate, though!
I’ve posted some other TurbSim timing results here: [url]TurbSim CPU Times]
