For calculating the electric field around the wires, we need meshing in the volume of the device and only on the surface of thin wires, not in the body of the wires. 

You can then just define the volume outside the wires. If the wires are very thin, Gmsh also allows you to embed curves (i.e. infinitely thin wires) directly in the 3D tet mesh.
