Hi, I'm using Star-Ccm+ version 6.02.007. I have to introduce a source term for turbulence dissipation rate in the k-epsilon standard low Reynolds model in order to partially rewrite the transport equation. Specifically, I have to rewrite model damping functions. I tried to do this with an user-code Region Profile written and compiled in C. I put Ceps1 and Ceps2 equal to zero and then I rewrote this terms thanks to the source term. But when I run the simulation the software seems not to consider the source term. Any idea? Maybe I'm using the wrong type of user-code.

Thanks
