How do I specify the DES turbulence model?

  I'm trying to do an aerodynamics simulation, but I don't see the option here to set the viscosity model to DES SST k-omega. How do I do set that?

  Ewen Discovery Live does not allow you change these types of details in the simulation. Please reference this post to learn more about the technology inside Discovery Live.
  
  If you would like to have control over the viscosity model and other more advanced settings try running the model in Discovery AIM. In the Physics task under Physics Options you will be able to change the turbulence model being used.

    Thank you. I might have to try that then.

    Does Discovery AIM use the GPU for the computations/analysis like Discovery Live does, or does it use the "conventional" CPU cores instead?
    
    Thanks.

    Ewen Discovery AIM uses the CPU for the analysis computation. The GPU is used for realistic material colour rendering and for display of results.

    Bummer.
    
    Thank you.
