Ansys Fluent 17 UDF Velocity Profile Update.
Hello,
I have been given a velocity profile UDF made for a previous version of ANSYS, which however does not work in Fluent 17. Any input on how to update this to work in Fluent 17 would be greatly appreciated. #include "udf.h" DEFINE_PROFILE(inlet_parab,thread,equation) { float x[3],y; /*face centroid coordinates */ face_t f; /* face identifier*/ float Vz; float C1 = 1.76E-6; float C2 = 2E-5; float C3 = 6E-4; float C4 = 2.1E-2; float Const = 1.79; /* loop on all faces belonging to the current thread */ begin_f_loop(f,thread) { F_CENTROID(x,f,thread); /*get the face centroid coordinates*/ y=x[1]; /*get the y coordinate */ Vz = -(C1*y*y*y*y)-(C2*y*y*y)+(C3*y*y)+(C4*y)+ Const; /*equation fit at 1.79 m/s to channel flow */ F_PROFILE(f,thread,equation)=Vz; } end_f_loop(f,thread) } Kind Regards, Phil. |
What error message do you get?

Hi Zbynek,
This is the error message I am currently getting. https://scontent.xx.fbcdn.net/t31.0-...30239760_o.jpg https://scontent.xx.fbcdn.net/t31.0-...50099802_o.jpg Many thanks for your response, Phil. |
As the error message says - you did not compile the UDF, or not at least for the double precision solver (dpp). Install Visual Studio and compile the code. You can find several threads about this on this portal.

Many thanks, I shall give that a go.
