I am making the manual of fluent "Modeling uniform fluidization in 2D fluidized bed" and in that udf uses one, the compiler is used, the windows is in define/User-Defined/Funtion/Compiled

The file c is called bp_drag, soon I give click him build and leaves this in the console

************************************************** ** Make sure that UDF source files are in the directory that contains your case and data files. If you have an existing libudf directory, please remove this directory to ensure that the latest files are used. 1 file copy. (system "move user_nt.udf libudf\ntx86\2d")0 (system "copy C:\Fluent.Inc\fluent6.1.22src\makefile_nt.udf libudf\ntx86\2d\makefile") 1 file copy (chdir "libudf")() (chdir "ntx86\2d")()

Done ************************************************** ***

now when I give click to the button load is when it leaves the error leaves this in this console

////////////////////////////////////////////////////// Opening library "libudf"... Error: open_udf_library: El sistema no puede hallar el archivo especificado.

Error Object: ()[/b] //////////////////////////////////////////////////////

The File c, I put it where this the case archives, but continues failing somebody can say to me because it leaves error, the version of the fluente is the 6.1

if you're doing the tutorial of the fluidized bed then you can use the interpret function in fluent instead of the external compiler. If you have to use the compiler function then you probably do not compile the UDF correct. I had also problems with that in the beginning, but the answer is at the fluent home page on the FAQ: compiling UDF. -lurk
