Degenerate Contact Points

Hi!

I'm getting an error when reading a mesh file into FLUENT 12

when doing a mesh check, i get the message

"9 degenerated contact points identified"

any idea why i'm getting this message and is it a problem?

thanks,

ash

I doubt this is a real problem.

It is when the surface mesh of two opposite Walls connects to a single node.

HI ,

degenerate contacts contacts is not a serious problem to run the solver.

its a warning . not an error.
