FMM-Yukawa: An adaptive fast multipole method for screened Coulomb interactions

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract A Fortran program package is introduced for the rapid evaluation of the screened Coulomb interactions of N particles in three dimensions. The method utilizes an adaptive oct-tree structure, and is based on the 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 packages are also available at http://www.fastmultipole.org/. This paper is a br...
