Hi,

I'm a undergraduate student and now trying a LES of turbulent boundary layer flow.

So I have a question.

How should I set the damain size and grid?
How large computational domain and how many grids are needed?

I'm assuming the culculation conditions as follows：
System: 3D Flat plate
Reynolds number (based on Uinf, vicorsity and the plate length L): 5 x 10^5
Turbulent transition: Tripping force

Any suggestions.

The minimum spanwise lenght should be properly prescribed otherwise the periodicity would ad an artificial constraint.

You can find some references in the textbook of Sagaut, I suggest also to see some of related papers here https://www.researchgate.net/profile...upta2/research
