Running libAcoustic function at later time step #109
Comments
Hi, @MarcusAW ! Yes, the library just calculates response to transient aerodynamic forces for given observer points. However, I would start your simulation from timeStart=1s, when you have already the developed LES flow (according to your question). |
Thank you for your help. On the matter of recording time, how long would be sufficient? In my approach, to save on memory, I record only for t=Distance between source and observer/flow speed. Once I record for t seconds, I save the results and rerun it again at a later time to get an average. Thanks, |
It's hard to suggest how long you should run your simulation, since the number of time slices (points) influences accuracy of acoustic spectrum. I think, you can just rerun the simulation several time and glue time series afterwards. |
Hello, I have a very simple question.
Suppose I run a LES simulation until there is a periodic behavior e.g. t=1s without libAcoustic. If I start a new LES simulation at that time step with the acoustic function, and set responseDelay=0 and timeStart=0, would the library be able correctly obtain p'?
Thanks,
Marcus
