This question doesn't relate to acoustics. Instead, it concerns about numerical simulation of flow field.

Is acousticlib use a lot of the simulation time?
I try to run turbulence flow through the cylinder with the RAS model.
It use a lot of time to finish it around 3 days.
Is it possible?
Thanks in advance
Im so worry about using it fist time i use openFoam for my master degree
project.

Hi, usually you need to run simulation 10 times longer than the period of the lowest frequency in your spectrum. For example, you want to catch frequency 1 Hz - then, you have to run simulation for 10 s or more.

which mean if i want to investigate the freq between the lower freq-upper freq (1Hz-10000Hz) i need to run the simulation using endtime at least 10 S ?

Yes, 10 or better 20-100 seconds
