Degenerated Edges at Interface

sasanghomi · October 22, 2019, 03:07

Hi,

I have faced a warning at an interface;
"Degenerated Edges have been detected and removed at interface...."
"This can be controlled with the real expert parameter GGI direct rel edge tolerance, currently set to 1.00000E-07"

I have used patterning techniques in Ansys Meshing in order to create the final mesh for my simulation.

Does it cause any problems in my simulation? (because it is just a warning)
Do you think patterning mesh brings about such issues?

BR,

I would have a close look at the mesh on the affected face. You might be able to continue and ignore it, but you do that at your peril. It is always best to fix meshing problems.
