I try to use the right

delta

for my IDDES simulation and I would really appreciate to have some suggestions about it. I've seen that the one normally use is

cubeRootVol

. But

cubeRootVol

doesn't seem to work with IDDES simulation. Plus, because my mesh has a ratio of around 8.8 (probably because of the cells from the layers) and

delta

is mesh related, I'm looking for the most appropriate

delta

to use. Here is what I got so far:
