compiling my UDF

Hi everyone: I wrote a program that it's needed compiling it as a UDF in Fluent. I add my source file and click on Load. When I compile the program (click on Load bottom) the Fluent sends me this error: "Error: open_udf_library: The system cannot find the file specified". I tried to add UDF.H file manually on the Header box and click on Build bottom to building the UDF library but it sends another error: "Error: open_udf_library: The system cannot find the path specified." At the end my Case and Data file together my Source file are in the same directory.
Best Regards, Farid, |

Hi, You have to add your source file, and then to build it. After that, you click on load.

Hi Max: Thanks for your favor. I do your guides but still Fluent sends me this error: "c:/seyedfaridhosseinizadeh/fluentrun"
Opening library "libudf"... Error: open_udf_library: The system cannot find the file specified. Error Object: ()" I'm looking forward to hearing from you. Regards, Farid, |

ok, look in your workink directory if you have a libudf folder. If yes, then you have to unload your libudf, with define/user-defined/functions/manage and then re-add your source, build and load (define/user-defined/functions/compiled)

Hi. I did them but still I have a problem. As you know I don't do anything with Header file. Maybe my problem is this. I don't know and really I'm confused. "c:/seyedfaridhosseinizadeh/fluentrun"
Opening library "libudf"... Error: open_udf_library: The system cannot find the file specified. Error Object: () Regards, Farid, |

Hi Seyed. I think you should change the name of source code for example " Code1 " . Do not allow the name has space or symbol.

--> Go to UDF manage menu and if any library is already loaded unload them. Then save the case file.
--> If libudf folder is there in you directory delete it. --> now try to compile and load the library. --> Still getting error, check directory has write file access. --> Still getting error, check for correctness of c Compiler installation. |

I got the same problem as yours when I run fluent in Linux. But in windows, every thing worked fine. But of course, I had to install visual C++.
After your built your Udf, do you find a folder named "liduf" in your working directory??? And you should also check that your fluent case is in the same folder as your UDF. when you built your UDF, do you get any error message??? |

Hi Guys,
If you are working on WINDOWS and installed Microsoft Visual studios.NET then, STEP 1: Place the source file in the folder which contain case & data file (place it in C-Drive) [Create a new folder in C-Drive and place the case and data files and the Source file (.c file)] STEP 2: Start --> All Programs --> Microsoft Visual Studio .NET 2003 --> Visual Studio .NET Tools --> Visual Studio .NET 2003 Command Prompt (it opens a command prompt) STEP 3: In the command prompt browse the folder in which the case & data files and the source files are placed STEP 4: Type "fluent 2ddp &" (it opens FLUENT console) STEP 5: File --> Read --> Case & Data Files (browse for the case and data files) STEP 6: Define --> User-Defined --> Functions --> Compiled STEP 7: Add the source files and click BUILD and then click LOAD Hope this will solve the problem for you people. If you have still some problems please feel free to contact me at duggirk@auburn.edu. Ravi |
