Sorry for the delay, I was out of the office last week. I often set the
reference potential "at infinity", i.e. where I can assume that the
fields are sufficiently attenuated, or on the boundary of a
geometrically transformed region. The important thing is to notice that
the problem, by nature, is not bounded, so that the conditions will
always influence the physical meaning of the solution.

My best,
