May 3, 2020, 06:34	Fluent Iterating very slow	#1
Sherif.farrag New Member Join Date: May 2020 Posts: 2 Rep Power: 0	Hi, I did 2D simulation on Ansys Fluent. iterating was very smooth and one iteration takes ~1sec as the mesh has 80 thousands elements. I did the same model but 3D I got 6 Million elements and one iteration takes ~15 minutes. is that normal ? knowing that thousands of iterations are needed from my 2D experience with the model! I have Intel Core i5 with 8 Gb Ram. Using parallel processing with 4 cores and single precision instead. The model is a simple supersonic flow over rocket nozzle. Any ideas? Is that normal?
