Undefined Value Found

I was runing a 2D model and came up with this error..
anyone can help me??

Undefined value found.

Re: Undefined Value Found

Hi

it looks like you have no material properties defined for a given domain or boundary, or that some BC values are missing, but it's not evident to say exactly what and where ;)

If you zoom in on the coordinates, you might identify the domain, or BC involved

Good luck
