Fast iterative solver techniques, developed to address the problem, suffer from convergence issues which become pronounced for large number of right hand sides as is the case for massively coupled systems ... The dense matrix is rendered sparse by applying multilevel multipole expansions, and the resultant sparse matrix is solved by a traditional sparse matrix solver. ... CONCLUSIONS In this paper a fast direct solver based on multilevel multipole expansions is presented. ...doi:10.1109/dac.2005.193791 fatcat:yqwj6ylzbbfsholkdwh6lnyjea
