CFD Online Discussion Forums - Compile UDF outside of Fluent with Visual Studio

Hello everyone,

So I used the search function but nothing helped for me. Our company guidline blocks the internal fluent compiler so I need to compile my code outside of Fluent.

I used the ANSYS help and followed the steps inside this document: https://ansyshelp.ansys.com/account/...mpile_tui.html

I know my c-code is fine, because someone who can use it in Fluent tested it.

So I modified the user_nt.udf and added the following (example for 3d_host):

Code:

FLUENT_INC= C:\Program Files\ANSYS Inc\v221\fluent\

FLUENT_ARCH= win64



CSOURCES = $(SRC)code.c

HSOURCES = $(SRC)header.h

VERSION = 3d_host

PARALLEL_NODE = none

My header-File only states the following:

Code:

#include "C:\Program Files\ANSYS Inc\v221\fluent\fluent22.1.0\src\udf\udf.h"

But everytime I compline the code in "x64 Native Tools Command Prompt for VS 2019" I get the following:

Stop.

So obvious he can't find the global.h file, which should be in \scr\main.

But above the folder is loaded.

So where can my mistake be?

Kind Regards,
