2 years ago Hi I am currently having this issue myself with the exact same error. I was hoping you could elaborate more on the work around and what you mean by "extend your sidesets too far"? My input file:

Bug Description
in opt
in devel: We properly catch it
Steps to Reproduce
extend your sidesets too far, use a FVDiffusionInterface
Impact
Minor impact since workaround is easy, just be more careful with your sidesets
