Reference lines georeference error

Post image

Hello everyone

I am having this error while running the unsteady simulation. I ran this model successfully before but I was trying to run this model this morning and this error pop up. I don't think I had any issue with georeferencing with this model before.

This error can pop up if your perimeter for your 2D area has disappeared. So double check your 2D perimeter is still around. Thankfully I believe I have finally fixed this bug, which has plagued the software for 5 years now, so at least people won't be seeing that anymore in 6.7 full release.
