HI Can anybody suggest me a C code for converting mass gfraction to concentration. I can access mass fraction form the solver but my udf works only on concentrations.

Secondly I need some advice on the above error I am getting. I am able to build (compile) the UDFs properly. But when I try to load them I am getting this error message Primitive Error at Node 1pen_udf_library : No such file or directory

Primitive Error at Node 2pen_udf_library : No such file or directory

Primitive Error at Node 3pen_udf_library : No such file or directory

I am using parallel version on Fluent .

any advice will be very helpful

Hi,

If the C source code file is not in your working directory , i mean the case file that you are working with then this error may arise..

Just try..
