Symbol lookup error

MatFras · January 18, 2022, 10:17

Hi to everyone,

I'm trying to run Converge in Linux with an Udf.
I followed the Udf Manual, and when I try to run the software I have an error:

converge-intelmpi: symbol lookup error: ./udf/build/libconverge_udf.so: undefined symbol: CONVERGE_operator_gradient_scalar_level_set

How can I solve it?

Hello Matteo,

You're probably using an older version of CONVERGE. That API routine present in your UDFs is not available in the version you're using. Please try your case with a newer version of CONVERGE (v3.0.24 is our latest version). There was a G-EQN related UDF update made in our v3.0.17 code (See our release notes for more information).

If you continue to have issues with your UDFs, even with our latest version, please contact 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 along with the UDFs and add the cfd-online thread, as reference.

Sincerely,

Thanks for your help, it worked!
