Extra edge created in Bends
 
hello

In Gambit, I used "Revolve faces" command to make a 90 degree bend of the pipe, After a 90 degree bend is made, it creates an extra edge joining the two vertices of the bend.

Does this extra edge has any implications? or its existance doesnt matter? Please guide.

Max, thank you for your reply.
The picture is attached. Extra edge is a blue line originating from ther vertex.
This is created when I used the "revolve face" command with an angle of 90 degree.
How can i omit this? or its existance has no influence on the mesh etc and/or why is it generated?

Thanks for your help.

ok, now it is clear :)
That will have no influence.

Could you please tell me why is it created? and how to omit it?

The line is created from the vertex.
If you sweep or rotate a surface, Gambit will stretch your topology: A surface will be a volume, an edge will be a surface and a vertex will be an edge.
If you want to make the line disapear, you need to omit the vertex.
But that : you won't be able to do it, since your circle needs a vertex at least.
Why it is bothering you?

Could you please say that if there seems any silhouette in the picture?

If you revolve a circular section, you only have two circle edges (source and target) and one edge on the outer surface. That edge is created from the vertex on your source circle.

Thank you Max and Husker.
