I have noticed that FEMAP reports that the gap between glue faces of some elements in gap pairs are overly large, even when there is no visible gap between the faces in the model. What is the reason for this false error and is there any way to fix it, if the geometry used to create the mesh is already in contact? What is the best way to know if this is actually causing an inaccuracy in the model.
I have only seen this error when connecting edge of shell elements to face of solid elements.

The gap between glue faces of some elements in gap pair 22 between
regions 37 and 35 seems overly large. The largest values are listed
