hi cfdiens

does any one know how to create a files that require to compile the udf.(not header files)libudf...etc

thanks in advance

actually what u want to know be clear . U CAN udf in C taking the help of help file. it should BE COMPILE OR INTERPRETE to link with fluent. u just write udf in c and open fluent and go define ->userdefine ->function ->interpreted/compiled it may help u

thaks for your reply

i have a c program.when i open the compile option there are two columns,one is source another is header files.for the source i can select the c source but wat about the headerfile? nothing is visible.

thank you

hi No need to go for the header file. JUST LEAVE IT AND PROCEED OK ALL THE BEST

hi i did the same but it shows like this

Opening library "libudf"... Error: open_udf_library: The system cannot find the file specified.

Error Object: ()

thank u

have u installed VC++ in ur sysyem properly ?

ya i have installed,the case and data files are in the same directory.i am using fluent 6.1 version will this make any difference?

thank u

send ur udf , case data file to me if possible, i will check it here

ok thank u

i got ur case and data send ur UDF (only) once again . it should be in .c form
