where i, j and k represent the residual equation number such that i∈[1,20],
index of the virtual node from the internal computational domain of the
PNP equations such that j∈[1,NV], and the overall index of virtual nodes
such that k∈[1, N], respectively. Therefore, Equation (7.58) is the

i
th
residual equation discretised at the
j
virtual node from the internal com-
putational domain, and its derivative is taken with respect to the func-
tion value at the
virtual node from the full computational domain. The
Jacobean matrix for the remaining residual equations is constructed as
