The nonlocal continuum dielectric model is an important extension of the classical Poisson dielectric model, but it is very expensive to be solved in general. In this paper, we prove that the solution of one commonly used nonlocal continuum dielectric model of water can be split as a sum of two functions, and these two functions are simply the solutions of one Poisson equation and one Poisson-like equation. With this new solution splitting formula, we develop a fast finite element algorithm and…

Efficient Algorithms for a Nonlocal Dielectric Model for Protein in Ionic Solvent
It is shown that the solution of the nonlocal dielectric model for protein in ionic solvent is unique, and can be found from solving two well-defined partial differential systems and one Poisson-like boundary value problem.
Comparison of a nonlocal dielectric model with a discontinuous model
We compare local and nonlocal dielectric models for the electric potential around a solute. We choose a water molecule as solute so that the comparisons can be related to the behavior of bulk water.
