Face with no cross edge

HI Brad,

I am getting an error that says: Face has no cross edge. I have embedded my fault in the center of the domain (pics below).
Fault has all the three sides marked as fault_edge to impose no-slip bc.


How to address this in V2.2?

Thank you

I don’t see anything obvious that would be causing this error.

Have you run mesh quality checks? Is the maximum condition number metric (available in Cubit and ParaView) less than about 3.0?

Hi Brad

Yes, I had done the condition number checks beforehand.

Here is the error log

Thank you

Do you get this same error with a coarser mesh? The easiest way to debug these types of issues is to coarsen the mesh and then examine in detail a run with the coarsest mesh that generates the error.
