Consider first the adjacent strong compartment. Discretizing at this compartment
yields

where ay is the radius of the transition compartment. After substituting in (??)
for vʃ, followed by much tedious algebra and gathering like terms, we arrive at the
following expressions for the voltage coefficients:
