wall slip-udf
hello thank you i wrote udf for slip on the wall: #include "udf.h" DEFINE_PROFILE(slip, thread, nw) { face_t f; begin_f_loop (f, thread) { cell_t c; double m =C_DWDY(c, thread); F_PROFILE(f, thread, nw) = 0.02* pow (m, 0.9); } end_f_loop (f,thread) } in fluent 6.0.0: first user defined---> functions--->interpreted UDFs d:\slip.c and then diplay assembly listing and then compile. then put this udf slip in boundary condition in the wall,there are not errors in these steps, but when i want to initialize solution and compute from inflow or any zones ,appear thie error: Error: FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. Error Object: () please guide me Yours faithfully Arash Avesta

hi
hi, i need a UDF for slip boundary condition at the bottom of the domain or at the ground (wall), case is just like a flow over a building. if anybody have sample UDF please share this, z is a vertical axis of my domain. thanks
