I am going to produce a box of isotropic turbulence and I have the following questions:
1-What should I use for initial conditions? (This is my main problem becauas I know we can not just set some sort of random numbers)
2-since it will be decaying and I want to stop it at a certain turbulence intensity, how should I know that I should stop the run to get my desired intensity?
3-Can I have a box with any aspect ratio? (Since I want to feed it as a precursor, I want it to have the same dimension as my main simulation inlet)?
I'appreciate to hear you useful comments.
They provide a velocity field that could be useful for your initial field.
