does anyone know how to solve this problem with the UDF in fluent? i have a laptop with windows 10 and I don't have "libudf" in the folder Fluent.

 

thank you

Can you compile a small UDF in Fluent outside the Workbench?

Example will be:

 

#include "udf.h"

DEFINE_ON_DEMAND(Hello)

{

Message0("nHello World!n");

}

yes, i tryed to compile this code in c++ and imported it in ansys but it displays the same error. do you know why? i tryed also to compile it in wordpad, but same error.

Have you tried to compile the lines I have sent? Have you installed the required compilers (Visual Studio)?

Please see this list of compatible visual studio applications using the link below and make sure you have a correct version installed on your system.

Hello ft,

To compile the UDF, we need to install VS in your windows machine. You need to set either the environment variables or run the fluent from VS command prompt and compile the UDF.
