Hi I have found the answer to my 1st and 3rd question after checking up CFD-Post user guide. 2nd question is still buggling me.
And also, in the case where I am much more interested in the low frequency range (<250Hz), which time step option should I go for? Since I have limited memory capacity, 200 time step is the most I can saved, as it is gonna take up around 50 GB of space. What is actually the best prectice for such selection?
Please advise me on this matter. Thank you in advance.
