This is an udf file used in the VOF tutorial..
Code:
#include "udf.h" #include "sg.h" #include "sg_mphase.h" #include "flow.h" #define PI 3.141592654 DEFINE_PROFILE(membrane_speed, /* function name */ th , /* thread */ nv) /* variable number */ { face_t f; real x[ND_ND]; real f_time = RP_Get_Real("flow-time"); begin_f_loop (f,th) { F_CENTROID(x,f,th); if (f_time<=10e-6) {F_PROFILE(f,th,nv) = 3.58*cos(PI*f_time/30e-6); } else F_PROFILE(f,th,nv) = 0; } end_f_loop (f,th) } #include "sg_mphase.h" and #include "flow.h" Isnt "udf.h" enought for the above code. Also do we need to evaluate F_CENTROID(x,f,th) in this case? |

I think "udf.h" coinains all needed to successfully compile your source file. You can find "udf.h" in the source folder within Fluent installed. F_CENTROID(x,f,th) needn't to be evaluated in your example.
I see you have tutorials files. Could you send me a copy of them (.msh, .c etc.) to my email. Thanks. |
