transport_k_epsilon

Inherits from: transport_equation_deriv

The (k-eps) transport equation. To resume from a previous mixing length calculation, an external MED-format file containing reconstructed K and Epsilon quantities can be read (see fichier_ecriture_k_eps) thanks to the Champ_fonc_MED keyword.

Warning, When used with the Quasi-compressible model, k and eps should be viewed as rho k and rho epsilon when defining initial and boundary conditions or when visualizing values for k and eps. This bug will be fixed in a future version.
