I have written a UDF code and saved it as UDF.C in my ntx86 folder. But when I want to interpret it in my fluent it shows the below error:
line 18: parse error
my line 18 is:
DEFINE_PROFILE(x_velocity,t,i)

is there something wrong with my udfconfig.h file? because I made some changes in my udf file and saved them in my udf.c file but didn't change anything else.

I think there is some mistakes in your line 18. I used this and it worked.

DEFINE_PROFILE(inlet_x_velocity, thread, position)

You can find the meaning of each one in FLUENT manual. (e.g. Inlet_X_velocity is the name of UDF)

Good luck
