Specifying an inlet boundary k-omega profile in CFX

Hello,
In the k-omega turbulence model I am familiar with, omega is the specific dissipation rate of turbulent kinetic energy. However, in CFX when I want to specify an inlet boundary profile for k and omega, my only options are to enter "Turb. Kinetic Energy" and "Turb. Eddy Frequency." Is the specific turbulent KE dissipation rate the same as CFX's "Turb. Eddy Frequency?" Can anyone explain this discrepancy between CFX's definition and the usual definition of k-omega? Thanks very much for any help. Max |
