Any document or experience of the comparisons of LES, K-e on tets and Hexs. Thanks!

Thank you very much for your input.

Well, maybe it isn't such a simple question.

Maybe if you pay somebody you get a faster responds

I know you may already have the answers. Appreciate if you can shed some light on this. This is not a serious problem for me since I have had the solutions already. I am curious if tets can do same kind of job just using more computational power. Anyway, we are on the way of getting it. My thinking is if tets lost second order of accuracy, then you have to have around 4 tets to compensate the loss, you need 4*4 tets to have one hex. Am I right? Thanks!
