 December 8, 2009, 07:51 Problem with interpreting UDF #1 New Member   Huw Woodward Join Date: Dec 2009 Posts: 2 Rep Power: 0 Hi, I am trying to write a UDF to define a temperature gradient along a boundary. When I try to interpret my UDF a message appears saying "line 7: parse error." which is the DEFINE_PROFILE(temperature_profile,t,i) line of my UDF shown below. I am relatively new to UDFs and can't see what is wrong with it. Can anybody help? Thank you. #inlcude "udf.h" #define TMAX 400.0 #define TATM 300.0 #define A 0.00001 DEFINE_PROFILE(temperature_profile,t,i) { face_t f; real x[ND_ND]; real r, k ,h; begin_f_loop(f,t) { F_CENTROID(x,f,t); k = x[0]; h = x[1]; r = sqrt(k*k+h*h); F_PROFILE(f,t,i) = (TMAX-TATM)*(exp(-(A/3)*r*r))+TATM; } end_f_loop(f,t) }

Hi,

This is typing mistake. Change #inlcude "udf.h" to #include "udf.h"

That all.
