  Hi Everyone,
  
  I was wondering if there are any resources (Documentation) on performing a Direct Numerical Simulation using Fluent.
  
  I have tried looking for it in the documentation but with no luck.
  
  It would be extremely helpful If anyone can guide me where to look.
  
  Thanks in Advance.
  
  Regards,
  
  Mostafa.

  Nothing is available which can be shared here. Actually and from modelling perspective andif you can afford it (computational efforts scales with Reynolds number power 3) you can try LES model set Smagorinsky constant to zero or using Laminar model with central differences. It is insane to do that for general problem ..especially if you do not have the resources.
