Hello Guys,
I am using LES to look at natural ventilation flows inside buildings. I have two point heat sources at the bottom of the building. I have run LES simulations for my case. I now want to run analysis on my case. To study the how the plumes developed from the plumes interact etc what sort of analysis should i carry out? I have read of doing an FFT analysis between the Cl and time. Can i also do this for velocity and time? Also Ansys post has an option for FFT.... then how come poeple keep on exporting their post results to matlab for analysis? Is Ansys own FFT not good enough? What other sort of analysis would you guys recommend to me. All your expertise will be of great help to me. Thanks
