Beam simulation issue

Hi lovely solidworks community.


I am using beam meshes to simulate leads on electronic components.  In most cases this proves to be successful.  However i've run into some difficulty with a particular design. 


The lead design is of a simple 90deg bend around a 2mm radius.  This is modelled using a single sweep feature.  When the part is converted to a beam and meshed, one of the straight elements detaches from the radius and connects directly to the top of the perpendicular lead leg. 


Is there a simple solution to this?  Its frustrating to have to return to solid meshing when the beam elements are proving to be fast and accurate in this application otherwise.  1st image below the part model, un-meshed:

Image below, part converted to beam and meshed, showing failure:

This is more than a graphical error, when the part is run the results assume that the lead is now connected at a sharp corner with the radius hanging loosely.  I have remodelled the design as a new part but still had the same error.


Part attached below.  Appreciate any comments/solutions to this!
