Hello everyone,
I am new to writing udf.
Currently, I would like to write a udf file to make the inlet volume fraction equal to the outlet.
The code is following.

however when I compiled it, the fluent shows:

Copied C:\Users\LKong\Documents ank\mt\1nz/C:\Users\LKong\Documents ank\mt\1nz\ioc.c to libudf\src
udf_names.c file in 2d_host is upto date.
(system "copy "C:\PROGRA~1\ANSYSI~1\v145\fluent"\fluent14.5.0\sr c\makefile_nt.udf "libudf\win64\2d_host\makefile" ")
1 file(s) copied.
(chdir "libudf")()
(chdir "win64\2d_host")()
# Generating ud_io1.h
ioc.c
..\..\src\ioc.c(21) : error C2143: syntax error : missing ';' before '{'
..\..\src\ioc.c(24) : error C2059: syntax error : '}'
udf_names.c file in 2d_node is upto date.
(system "copy "C:\PROGRA~1\ANSYSI~1\v145\fluent"\fluent14.5.0\sr c\makefile_nt.udf "libudf\win64\2d_node\makefile" ")
1 file(s) copied.
(chdir "libudf")()
(chdir "win64\2d_node")()
# Generating ud_io1.h
ioc.c
..\..\src\ioc.c(21) : error C2143: syntax error : missing ';' before '{'
..\..\src\ioc.c(24) : error C2059: syntax error : '}'

Done.



I did not found I miss the ; before the { or }.
could some one help me with this, thank you very much

}

First of all: there seems to be a space in your folder name. ("Documents ank") I don't see it giving any problems now, but it can give you problems later, and it is safer to do it without space, for example with an underscroe. ("Documents_ank")

Secondly: you wrote "beginf_f_loop" where you meant "begin_f_loop".
