Phillip Guest Posts: n/a	Hi, I've just started working in CFD. Could anyone help me understand DNS ? I've few notions: 1. DNS is computationally time consuming 2. We need a very fine grid to carry out DNS (how much fine my grid should be) 3. I can get 1/7th power law profile using DNS of pipe flow for Re>4000 Are my notions correct ? Thanksa lot
