Hi everyone, and thanks for support
I am newpe to run ideal case Large eddy simulation LES, I am wondering what is the maximum resolution we can set to run LES in a stable mode?
in other words, what is the minimum dx, dz and dt to have stable LES simulation?
Cheers
Ahmed
 
Ahmed,
I'm not sure if we know values for those, but I can tell you that the minimum dt should be no more than 6xDX. You can play around with a few different values, running small tests to see if they are staying stable.
