Association Problem
 

Hello,
In 3d pipe junction tutorial problem i am getting error like this " No edge selected for association" what is main cause for this.what does association means in ICEM CFD

It makes the blocking to follow the geometry features e.g.

vertex(blocking) will follow the point (geometry)

edge(blocking) will follow the curve (geometry)

face(blocking) will follow the surface (geometry). By default faces will be associated to nearest surface without explicitly associating it.

volume mesh is generated automatically.
