could you please elaborate the steps of the procedure?
it would really be helpful. Thankyou.

I have actually tried this and the code is compiling but are the results easily accessible?

use ANSYS 2021 R1, udf is compiling easily. Also, it has built-in compiler.

can you send me download link? and is there any other way of doing it(without installing this new version)?

thanks in advance

I have encountered the same problem regarding nmake. Adding it to the windows environment variables path and running Fluent without command prompt gave me another error (Fatal Error C1083). After some searching, I managed to solve it and now UDFs can be compiled without running from command prompt! So I wanted to share my steps to hopefully help others:

1) Install Visual Studio (version 2019 for me)

2) Go to "C:\Program Files (x86)\Microsoft Visual Studio\2019" and type in the search bar "nmake" to find where nmake is located.
For me, it's located in "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.25.28610\bi n\Hostx64\x64". This is your nmake location.

3) Go to Control Panel->Settings->System Settings->Environment Variables->System Variables
and find "Path", then click on "Modify"

4) Click "new" and add your nmake location to the path. Then click ok.

5) Open Fluent, open a Fluid Flow (Fluent) component, and right click on "Setup" -> Edit.
Click "+Show more Options", then go to "Environment".
Copy the udf.bat location (for me it's "C:\Program Files\ANSYS Inc\v182\fluent/ntbin\win64/")
and paste it in the explorer to open it.

6) Right click on "udf.bat"->Open with Notepad++ (as administrator).

7) Paste the following text (but make sure the folder paths and VS version are correct for your own computer). Careful to paste the following texts in their appropriate locations:

Paste this text before "echo "No MSVC compiler detected!""

echo trying to find MS C compiler, version 19....

set MSVC_DEFAULT=%ProgramFiles(x86)%\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build
if exist "%MSVC_DEFAULT%\vcvarsall.bat" set MSVC=%MSVC_DEFAULT%
if not "%MSVC%" == "" goto msvc_env19

and further below you paste this text before ":ms_c_end":

:msvc_env19
set MSVC_VERSION=19
call "%MSVC%\vcvarsall.bat" x86_amd64
goto ms_c_end


8) Save the udf.bat file, and restart Fluent. Now you should be able to directly compile codes without any problems and without having to run through command prompt

sir, i am getting this error but i get confused while i am following your solution:
explain to me here plz"5) Open Fluent, open a Fluid Flow (Fluent) component, and right click on "Setup" -> Edit.
Click "+Show more Options", then go to "Environment".
Copy the udf.bat location (for me it's "C:\Program Files\ANSYS Inc\v182\fluent/ntbin\win64/")
and paste it in the explorer to open it."

this is solution for fluent version up to v19.2

thanks,

yes I am using also v195, I think that it should be solved, can you try to explain again this statement you wrote while solving this issue<<Copy the udf.bat location (for me it's "C:\Program Files\ANSYS Inc\v182\fluent/ntbin\win64/")
and paste it in the explorer to open it.>>

when I reach at this step, I get lost. thanks

[AlexanderZ]

that's not my guide, whatever

5) Open Fluent, open a Fluid Flow (Fluent) component, and right click on "Setup" -> Edit.
Click "+Show more Options", then go to "Environment".
Copy the udf.bat location (for me it's "C:\Program Files\ANSYS Inc\v182\fluent/ntbin\win64/")

go to this directory, find there file "udf.bat"

6) Right click on "udf.bat"->Open with Notepad++ (as administrator).

7) Paste the following text (but make sure the folder paths and VS version are correct for your own computer). Careful to paste the following texts in their appropriate locations:

Paste this text before "echo "No MSVC compiler detected!""

echo trying to find MS C compiler, version 19....

In all fairness, I see this problem has been around since quite a long time and sadly ANSYS hasn't done anything about it despite tons of complaints. A more simplified and robust compiler should do, but alas it seems they simply don't want to bother.

I can fully relate to what you are feeling. I felt the same way, before following what k_ina posted. Make sure you've installed the C++ related workload. (In VS, go Tools menu=>Get Tools and Features=>Install the Desktop Development With C++ workload). It's only then, you will see the nmake.exe file and also the vcvarsall.bat file. After installation, you can then follow what @k_ina posted
