Dear Vinerm,
Thank you. I don't find Developer or x64 or x86 command prompt. Neither do I find it when I search the install folder of VS2010.

This might also be version dependent. Search by command or vs and then look within the results if it shows anything that is command prompt from VS.

Try compiling the usual way with the file that I have attached. Its the same file with minor modifications.

Dear Vinerm,
I got the developer command prompt and opened it in 64bit. But I couldn't cd the path to the folder containing the fluent.exe.
Thank you very much.

In Windows, you cannot cd to a path directly if it is in a different drive. First, you need to change drive. Best would be to go the directory where you have your UDF source and case file. If it is F:, then simply use cd. If not, then use the name of the drive. E.g., if you want to change to drive c, then give command c:. Once in the directory where you have the file, use full path to start Fluent, i.e., C:\Program Files\Ansys Inc\v180\fluent\ntbin\win64\fluent.exe

Dear Vinerm,
I have tried both methods you mentioned. Unfortunately, both failed eventually. Still puzzled.
Thank you.

Try with a very simple program

#include "udf.h"

DEFINE_EXECUTE_ON_LOADING(test, libtest)
{
#if !RP_HOST
    Message0("This one works\n Hopefully\n");
#endif
}

Dear Vinerm,
The simple code is successful. Then the former UDF success too. It is really amazing!!!
Thank you very very very much from my deep heart. Salute!!!

Nice to know that it finally worked.

Dear Vinerm,
Thank you. It is my first time that I posted a thread here and received your nice respond. It is no exaggeration to say this is an awesome experience. Now I am attempting to do simulation in HPC environment.
Thank you again.
