Hi I have a question about coupling simulation of solidification and turbulence. For simulating the flow field in the mushy zone between liquid phase and solid phase, I added a source term to the governing equation of momentum by volume force, but I found I can't add source terms to turbulent kinetic energy equation and turbulent energy dissipation equation. So where or how can I add souce terms to turbulent kinetic energy equation and turbulent energy dissipation equation?
Thanks in advance for your help!
