Is this the one? Or you could provide me with the exact function that you are looking for.
The following UDF, named user_log_law, computes U+ and dU+, and dY+ for laminar and turbulent regions using DEFINE_WALL_FUNCTIONS. The source code can be interpreted or compiled in FLUENT. /************************************************** **************** User-defined wall functions: separated into turbulent and laminar regimes /************************************************** ***************/ #include "udf.h" DEFINE_WALL_FUNCTIONS(user_log_law, f, t, c0, t0, wf_ret, yPlus, Emod) { real wf_value; switch (wf_ret) { case UPLUS_LAM: wf_value = yPlus; break; case UPLUS_TRB: wf_value = log(Emod*yPlus)/KAPPA; break; case DUPLUS_LAM: wf_value = 1.0; break; case DUPLUS_TRB: wf_value = 1./(KAPPA*yPlus); break; case D2UPLUS_TRB: wf_value = -1./(KAPPA*yPlus*yPlus); break; default: printf("Wall function return value unavailable\n"); } return wf_value; } |

Thanks for your help,
I need a function to define the drag coefficient, it is named "magelli correction" and is necessary to simulate a turbulent eulerian granular flow. I got a paper from fluent where it is explained. It also says that the UDF is available in fluent users (Fluent UDF Archive UDF52). I hope you have information enough now, Thank you again! |
