Hi, I am a beginner at UDF and I want to know UDF. But in Net, I see that many users have great problems in linking between Ansys Fluent and Microsoft Visual Studio. Why does this happen?

My system consists of the following:

-Window 10 x64 interprise

-ANSYS Fluent 17 x64

What version of Microsoft Visual Studio should I use until I don't face with problem?

What steps should I follow until I don't face with problem?

I am grateful that guide me in these cases.

Thanks.
