Description

Abstract Electric forces play a key role in the conductance of ions in biological channels. Therefore, their correct treatment is very important in making physical models of ion channels. Here, we present FORTRAN 90 codes for solution of Poisson's equation satisfying the Dirichlet boundary conditions in realistic channel geometries that can be used in studies of ion channels. For a general channel shape, we discuss a numerical solution of Poisson's equation based on an iterative technique. We also pro... Title of program: bics Catalogue Id: ADIT_v1_0 Nature of problem The program calculates the potential energy of and force on an ion in the vicinity of a model ion channel. It can include the effects of an externally applied field and fixed charges other than the ion. It can also calculate the electric field and potential in the absence of an ion. Versions of this program held in the CPC repository in Mendeley Data ADIT_v1_0; bics; 10.1016/S0010-4655(98)00090-3 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
