Yes, I selected axisymmetric Swirl. I checked whether C_W(c,t) returns the swirl velocity component, and it does. The program runs just fine when I use C_W in the udf. But, when I use C_W_G(c,t), I receive the error "999999: mpt_accept: error: accept failed: No error" and the program closes immediately. This happens also if I do the initialization before I select the user-defined turbulent viscosity in the k-epsilon model.Â
