  /forum/forums/topic/problems-loading-udf-for-moving-mesh-in-fluent/
  
  according to this post, I installed Visual Studio Community 2015 and SDK. But nothing changed.
  
  Do you have any suggestions?

  SDK is not really required here. Just open x86_46 Cross Tool Command Prompt from VS Program launch Fluent from there, try to compile.

  I solved the problem.I applied this:
  
  "Set the correct environment variables. Browse your way through the Windows system control to 'System'. There you will find a section 'Advanced system settings'. In the following dialog go to the 'Advanced' tabulator and click on 'Environment variables' (lower right corner). Go through the 'System variables' list and search for the 'Path' entry. Add the following to the variable: C:Program Files (x86)Microsoft Visual Studio 10.0Common7Tools;C:Program Files (x86)Microsoft Visual Studio 10.0VCbin;C:Program FilesANSYS Incv120fluentntbinwin64"
  
  In my system it is like this: C:Program Files (x86)Microsoft Visual Studio 14.0Common7Tools;C:Program Files (x86)Microsoft Visual Studio 14.0VCbin;C:Program FilesANSYS Incv180fluentntbinwin64
  
  Then, problem is solved.

  Hi!
  
  I have the same problem, did you create a new variable or did you edit one of the existing variables??

  Hi Martita!,
  
  I am not sure but as far as I remember, I found the path from system variables then I added a new variable.

  HinI also have the sane problem. I tried to use your solution but my visual studio (2017) does not include any folder named VC (for second path that you said should be past in variable). Do you know what is wrong by chance?n

  Update to at least release 2020R2 and use the built in compiler in Fluent.n
