I think part of the answer depend on your model size and your computer. I typically run 4 simulations at a time using the batch run. [Flow Simulation | Solve | Batch run]. At the bottom of the Batch run window there is a box to change the maximum simultaneous runs.
The batch run method will run all you configurations in parallel instead of serial.
Hope this helps.
Thank you very much for your answer. I tried this but do not see solver folders for other analysis. Why I do not see separate folders for each analysis?
When you setup a simulation it creates a new folder. Are you saying those folders aren't there? Each set of files will be in the folder for that configuration.
I agree with Chris. When you start the simulation it should create folders for each configuration automatically. For me these folders are always created in the same folder that the assembly file is in.
If you don't have any other configuations, where are the files placed?
