Using RANS in SOWFA codes

Hello all,

I’d like to run Reynolds-Average Navier Stokes (RANS) models in the SOWFA cases instead of the LES models that are typically run. I haven’t found any literature on this. There are RANS solvers already in OpenFoam, but I’m not sure if it’s sufficient to just change to one of them. Has anyone here done something like this already, and if so, could you point me towards any literature that has come out of that, or perhaps send me examples of your code?

If not, does anyone have better intuition than me on how to:

  1. set initial conditions of the turbulence model
  2. change the boundary conditions
  3. figure out what to do to the timestepping?

Thanks in advance!
