The following two cases are different just because fluent runs on two different machines. Would you kind enough to tell me what makes this different and how can I make the wrongly-run machine work fine?

Creating library libudf.lib and object libudf.exp

From the line:

LINK : fatal error LNK1181: cannot open input file "fl6118s.lib" NMAKE : fatal error U1077: 'link' : return code '0x4a' Stop.

I'd think the linker doesn't know where is the file "fl6118s.lib", or maybe it isn't on the hard disk.

Hi

ap

Try these steps to compile a udf in fluent:

I believe you are using the Microsoft visual c++ compiler, try running vcvars32.bat in a command window (this will set all the environment variables up).

Next compile the udf source file in fluent.

Next run nmake in the newly created folder: ..\libudf\ntx86\2d\

Then load(build) the udf in fluent.

These steps should allow you to compile and load the udf in Fluent.

I have solved the problem.It is caused by the difference of the versions of compiler and linker. Thanks for all of you and your suggestions.
