Could you explain how in CFX the Turbulence Eddy Frequency and the Turbulence Eddy Dissipation are
correlated? Is it defined as omega = epsilon /k ?

From the fact that the turbulence eddy viscosity is defined as

in k-epsilon model: mu_t = C_mu*rho*k^2/epsilon
in k-omega model: mu_t = rho*k/omega

we can conclude that

Turbulence Eddy Frequency = omega = 1/C_mu*epsilon/k .
