When i have a mesh and i have just the 0/ folder, its stagnant field inside... not really vacuum :D Before i run my LES, if i want to check my mesh to see if it has a good yPLus, then how do i do it...

A general question - If I have a simulation yet to run, but i want to decide if my yPlusLES is good, then can i just set the internalField for U in 0/U to be the inlet velocity...

Bernhard: The new C file and the reason for it makes sense. If for example, the first cell is say about y+ = 1.5 and we target y+ =1, then a first step would be make a y+ =1 but the next cell then...

Hi, When you use this utility, can it be done before any computations? I have a case where i plan to generate a steady state RAS solution and then use that as an initial state to do a transient...
