Hi,

I have a problem during compiling my UDF file. I'm using ANSYS 18.1 and visual studio express 2012.

I follow the step in youtube link = https://www.youtube.com/watch?v=OPfgkORSESQ&t=84s

Hopefully someone could help me.

Below is the error that appears in the Fluent.

Thank you.

compiler is not connected to fluent, that why nmake doesnt work
run fluent from Visual studio command prompt
