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?
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.
