为求解Poisson-Nernst-Planck(PNP)方程的数值解,提出一类径向基函数配置法。该方法利用径向插值基函数离散正则化PNP方程,通过Sobolev空间Hk(k〉n/2)和谱半径技术验证算法的收敛性和数值误差的稳定性。结果表明,该方法是有效的。
In order to solve the numerical solution of Poisson Nernst-Planck equations, a radial basis function collocation method is proposed. In ibis method, the radial interpolation basis function is used to discretize the regularization PNP equa tions. The convergence of algorithm is discussed in Hk (k 〉 n/2) and the stability of numerical error is verified by the spec tral radius technique. The resuhs show that the approach is effective.
