some udf compliation issues need your help

BW1211 · July 29, 2021, 10:55

Hello everyone，I am sorry to disturb you all, I want to ask you some udf compliation issues.
I have been simulating the ash deposition in a boiler through FLUENT, and a udf is used here. But what puzzles me is that the same udf compiles successfully on my laptop, but is can not compile well on the desktop. (The version of Fluent and VS is also the same in the two computers.).I have tried the following solutions, but the problems are still here.
(1) Change the installation location of VS in the udf.bat. (Many versions of VS have been tried: VS2010/2012/2013/2015)
(2) Add some sentences in the vcvars64.bat (set INCLUDE >> path.txtset LIB >> path.txtset PATH >> path.txt) and then add the path in the system environment.
(3) Open Fluent through VS command prompt.
There is no problem with udf itself, but it can not be compiled successfully on the desktop computer. This problem has troubled me for a long time. I hope to get your guidance.
Thank you for your patience to read these questions.
Wish you a happy life.

do you have

Code:

#include "udf.h"

in the very first line of your code?

It is the error after loading. To see compiler errors, look at your screen after you click "build".
