Can anyone help me understand the cause for this error, please?
I can't figure out why these lib files are shown in the error output. I've searched various pieces of the message and found nothing relating to this issue I'm seeing.

I apologize, I intended to put this in the meshing forum.
Regardless, I've tinkered with mesQualityDict and magically things work now. I am unsure how my changes effected the issue, which is very frustrating.
