Built-in compiler doesn't create libudf.dll

Hi! Fluent Built-in Compiler doesn't create libudf.dll. Folders (src and win64) are created, but they haven't libudf.dll. What may be wrong? Fluent 2022 R1. UDF is from a tutorial.

This problem is solved. Working with .exe files was blocked. The System administrator has unblocked rights on the computer and the problem has gone.

Hi Sergey,

I don't see a libudf.dll in the libudf folder. I do see src and win64. Is libudf.dll created once the fluent simulation runs or immediately after the libudf folder is created?

Thanks

Hello. libudf.dll is created after compilation of an UDF (Functions->Compiled...->Build). It needs to be compiled once. Closing Fluent doesn't remove the libudf folder and its content.

Hi Sergey, Thanks for the comments. I am getting a warning upon compiling my UDF with the built-in compiler.

scons: warning: No version of Visual Studio compiler found - C/C++ compilers most likely not set correctly
File "C:\Users\....\libudf\win64\3ddp_host\SConstru ct", line 20, in <module>
Compiler path: "C:\PROGRA~1\ANSYSI~1\v241\fluent"\ntbin\clang\bin \clang-cl
Linker path: "C:\PROGRA~1\ANSYSI~1\v241\fluent"\ntbin\clang\bin \lld-link

After compiling, I click load and then initialize and run the simulation. Then I get a fatal error:

================================================== ============================

Node 3: Process 10824: Received signal SIGSEGV.

Error in the fluent (fl) process : ended abnormally

Other than checking Setup Compilation Environment for UDF in Fluent Launcher do I need to anything else. Thanks.
