Hi Fedor,
Thank you for the prompt reply. For DNS, I use BGK with D3Q27 descriptor. I was using RLB for only LES, which gives good results.Thanks for the suggestion regarding vortex inlet, I’ll use that. However, it is the significant lack of mass conservation in DNS (BGK) that worries me the most. This makes the simulation not useful.
Best,
Nipin
