Abe & Zhangkun Linpar has a utility that allows you to use parallel, insulated wires in a 2D field solver by assigning one of the wires to be the ground. It is intended for insulated wires in a flat cable configuration, but you could use the insulator dielectric Er=1 (for vacuum/air) and then increase the capacitance matrix values by the Er of any surrounding dielectric material.
