hi,when i compile any code with '#include <udf.h>'in its first line,copmuter always tells me that no such file or directory.why?help me pls!

thanks!

include what? do you write the name of the file you want to include? is it in the programme directory?

code is following:

#inlude"udf.h" ......

OK, if it is written exactly as you have it here then where is the space between the #include directive and the file name. If the file is not in the main directory you can either copy it to the main directory or write the complete file name including the path e.g. <c:\xxxx\xxx\udf.h> In C language the <xxxx> and "xxxx" have different meanings to the parser. Check any C language book for the differenc. Hope that will solve your problem and Good luck

hi,error still exist. the case is following: #include "C:\FLUENT.INC\FLUENT\fluent6.0\client\src\udf .h" DEFINE_PROFILE(inlet_xv_sinusoidal, /* function name */

thread, /* thread

nv) /* variable number */ { face_t f; real flow_time = RP_Get_Real("flow-time");

begin_f_loop (f,thread)

{

F_PROFILE(f,thread,nv) = 20. + 5.*sin(10.*flow_time);

} end_f_loop (f,thread) }

Compiling... inlet_xv_sinusoidal.c c:\documents and settings\管ç�†å'˜\æ¡Œé�¢\inlet_xv_sinusoidal.c(1) : fatal error C1083: Cannot open include file: 'C:\FLUENT.INC\FLUENT\fluent6.0\client\src\udf.h': No such file or directory Error executing cl.exe.

inlet_xv_sinusoidal.obj - 1 error(s), 0 warning(s)

why?

its something to do with your path settings of the header, please ask to fluent support about this, they are best person to advise on this issue.

Call your support engineer and if possible post the reason for that, you have forced the compiler to read the file where it is residing, wish happy ending to that situation.
