I am trying to compile a udf library for user_merit_function. I have user_dynamic_routine.c and user_merit_function.c in my src folder and the necessary header files in input folder. When I try to compile it, i am getting a warning "unrecognized openmp" in shared.h file. Although it gets compiled completely, while running the simulation I am getting an error "undefined symbol: user_outputs_init" while loading libconverge_udf.so.


What is this error about? Am I missing some file in src or input folder?


Please do help!

Thank you.

Hello Shoaib,

user_outputs_init is present in user_outputs.c. Please check your udf.in file if user_out_flag has been enabled. You would require user_outputs.c in your src folder when you compile the UDFs if you want to enable user_out_flag. Also verfiy whether user_outputs_init is being called within user_merit_function.c.

It might be best for you to forward your case to support@convergecfd.com. Please use your official email for all correspondence with Convergent Science. Please mention the issues you are facing, attach your case setup and add the cfd-online thread, as reference.

Thank you so much for the reply. It solved the previous error but now I am getting a new error named: 'undefined symbol: user_ga_merit_function'. I will send an email to the email which you have given now with the screenshot of library compilation too.

Best Regards,
Shoaib
