the wire is not electrically connected to a metalic face

oussama1

i constructed the cable shown in the attached image. the bare above wire should be electrically connected to the metallic shield. however,  feko does not consider the wire and the shield surface connect even i have union them together. what do you suggest ?  does there is a way to make the wire with a given radius connected to the shield surface taking in consideration the wire radius. (it means the shield surface is far from the wire center by rw (wire radius) as shown in the image).

It's difficult to judge just from an image,

If the 3 wires running into the Y direction are made from lines (which will mesh into wire segments) then their 'surfaces' (defined by their radii) are purely analytical. You cannot connect to them. 

If you draw a line going into a cylinder and Union, then there would be a connection to the cylinder surface plus a small remaining section of the line would remain on the inside of the cylinder.
