you can define the fluid by creating a seperate fluid properties entry in the materials menu. then import the viscosity curves as a .crv file from notepad or excel. when you select the solver make sure you envoke the turbulent compressible k-e model.

you will notice convergence oscillates but dont worry just keep waiting for the residules to converge.

peace brother! smoke em if ya got em!
