Hello
I got some problems with my UDF file when I compiled it in Fluent.
I hope someone could help me ,the error text is written below:

cpp -I"D:\Fluent.Inc\fluent6.3.26/src" -I"D:\Fluent.Inc\fluent6.3.26/cortex/src" -I"D:\Fluent.Inc\fluent6.3.26/client/src" -I"D:\Fluent.Inc\fluent6.3.26/multiport/src" -I. -DUDFCONFIG_H="<udfconfig.h>" "C:\Users\reza\Desktop\1234.c"
Error: udfconfig.h: line 22: parse error.

the udf is written below:

It works for me. Note that you have omitted something when you go the the next line in the code you have attached. I have corrected it but I don't know what you meant. Check it.
