Hi everyone, I am an undergrad student doing my thesis on aeroacosutics using Fluent.
I am running an airfoil CFD simulation, recording the acoustic signals using the FW-H equation in the native GPU solver. The output of my ASD files however is different to that when run in the standard CPU solver (CFD Pro/Premium), and I am struggling to comprehend its format. I am new to using the GPU solver, and have found many things to behave differently to the standard solver. Furthermore, I am having troubles reading these files once the simulation is complete. I have 2 acoustic sources (ID 11 and 26) which are constructed from 4 faces and 2 named selections (ID 11 -> 1 Face, ID 26 -> 3 faces). I have 7 recievers, and am saving data every timestep and files every 500 timesteps (explaining the "5001-1-5500" etc). What I am most confused about is the 4.0, 4.1, 4.2, 4.3 suffixes being generated, meaning that I end up with 4 sets of data, this wasn't the case in the CPU solver where only 1 set of data was produced. Additionally, the index file doesn't seem to match up with the files being produced. If anybody is familar with the GPU solver within fluent and could shed some light on my situation that would be great!
Thank you to all who respond!
