| 英文摘要 | A Fortran program package is introduced for rapid evaluation of the electrostatic potentials and forces in biomolecular systems modeled by the linearized Poisson-Boltzmann equation The numerical solver utilizes a well-conditioned boundary integral equation (BIE) formulation. a node-patch discretization scheme, a Krylov subspace iterative solver package with reverse communication protocols, and an adaptive new version of fast multipole method in which the exponential expansions are used to diagonalize the multipole-to-local translations The program and its full description, as well as several closely related libraries and utility tools are available at http //lsec cc ac cn/-lubz/afmpb html and a mirror site at http //mccammon ucsd edu/ This paper is a brief summary of the program the algorithms, the implementation and the usage Program summary Program title AFMPB Adaptive fast multipole Poisson-Boltzmann solver Catalogue identifier AEGB_v1_0 Program summary URL http / lcpc cs qub ac uk/sunlmaries/AEGBvI.0 html Program obtainable from CPC Program Library.
