  DL 19.1 has improved the accuracy of fluid analysis greatly. Steave posted that the fluid analysis solver is a Lattice Boltzmann method with LES turbulence. Is this changed at 19.1? If it is LES, I think that it is necessary to use GPU with more VRAM in order to capture finer eddies.

  Hello Miyado
  
  There are improvements in the fluids algorithm due to which you are noticing the improvement in results.
  
  A GPU with more VRAM and higher Fidelity setting will give you much better results.

  Steave updated the content of the post. Thank you.
  According to the post, fluid analysis solver was changed to finite volume method with LES turbulence.
  This is helpful for me.
