Hi gays,
when I build my udf I see no problem as you can see bellow, but when I load it, I see this message:

Opening library "C:\Users\Desktop\fluent\libudf"...
Error at Node 0: Error code: 126

my computer work with windows 7, and VS 2010, fluent 19.0 on my system
any body can help me. I am very confused to waht do I do.



Copied C:\Users\Gigabyte\Desktop\fluent/C:\Users\Desktop\fluent\burner.c to libudf\src

Done.

you are trying to load code, which was compiled on other system for other fluent version(most likely)
Recompile your UDF

It appears that you are trying to load from a wrong location. Look at the first message, name is given as C:\Users\Gigabyte\Desktop\fluent/C:\Users\Desktop\fluent\burner.c

It appears that libudf is not located in the same folder as case file; it is not necessary but if it is not the case, then you have to provide full path to load. Second, go inside libudf and check if it has .dll files inside 3d_host 3d_node folders. If not, then library is not compiled. If it exists, then just copy libudf to the folder where case exists, use only the name of the library while loading, and it should work. If it does not, then please share a complete message showing compiling and loading.
