I am trying to load a udf library into fluent and consistently get error code 126, I have successfully loaded other udfs into this version of fluent and have attempted to load this library into both fluent 20.0.1 and 18.2 with no success. I have been tried compiling with the default compiler and also with Visual Studio 2019. I have also tried loading fluent without parralel processing enabled. I suspect that this error is due to having tensorflow as an include library, I have linked tensorflow as shown below
Code:
#include "C:\Program Files\ANSYS Inc\v201\fluent\include\tensorflow\c\c_api.h" 
#pragma comment(lib, "C:/Program Files/ANSYS Inc/v201/fluent/lib/tensorflow.lib")
When building my code I get a few warnings but no errors and these dont seem to be what is blocking the loading.
Code:
C:\Program Files\ANSYS Inc\v201\fluent\include\tensorflow\c\c_api.h(935): warning C4190: 'TF_NewWhile' has C-linkage specified, but returns UDT 'TF_WhileParams' which is incompatible with C
C:\Program Files\ANSYS Inc\v201\fluent\include\tensorflow\c\c_api.h(891): note: see declaration of 'TF_WhileParams'
C:\Users\Tom\Desktop\DeepLearningFLUENTsims\PlanarJet1.6_tempslice_files\dp0\FLU-1\Fluent\libudf_vrr\src\StaticLib_VRR2.cpp(71) : warning C4700: uninitialized local variable 'cx_cell' used
If anyone has any ideas on solving the error 126 I would appreciate it

AlexanderZ will become famous soon enoughAlexanderZ will become famous soon enough
there is a special workflow for linking external (precompiled) libraries to UDF
you may find it in ANsys Fluent Customization manual

Hi,
Have you solved this problem? I'm now facing the same issue when loading an external library. I'm now using Fluent 19.3(2019r1) and VS 2017. I didn't get the error message when compiling the udf, but received error 126 when I tried to load the udf.
