Hi developer, I recently got the following error when building a dmp solver with mfix, but it didn’t occur before, why is this？

Traceback (most recent call last):

This is an unusual error which I haven’t seen before. Can you upload your project? Go to the main menu, select “Submit bug report” and upload the resulting ZIP file.

Also note that the solver build mechanism has been simplified since mfix-21.4, you may have better luck if you upgrade to the most recent (22.4.3) version of MFiX.

Thank you very much! Charles,I modified the mfix version,build successfully.
