Invariably, it IS done with 3d models, those not being particularly amenable to simple analytic solutions. Unfortunately, finding a dye that changes state at some convenient field isn't so easy. What you usually do is use an insulated probe (because what you are really measuring is voltages resulting from current flow, which happens to be distributed in the same way as electric field)

For 2 D problems, rubber sheets and posts have also been used.
