Hypermesh about boundary layer

Recommended Posts

Hi.

There is a problem with my case. I created an outer circle with the diameter 0.0074mm and the inner circle is 0.007mm. Create a surface between the two circles in order to generate the boundary layer.  The lines from the iges file were deleted after the meshing is OK.   I want to create the boundary conditions such as inlet, outlet etc.. I use Tools-edges-find edges to create edges based on the mesh. However, 2 circles are still generated as edges. One can see the blue line and the red line. I don't want Hypermesh to find the red line. How can I do that? Thanks~~~~
