Constructing adaptive boundary elements for the Poisson-type nonlinear problem Song Qing Xu" & Norio Kamiya^ "Graduate School of Human Informatics, Nagoya University Nagoya, 464-8601, Japan * School of Informatics and Sciences, Nagoya University, Nagoya, 464-8601, Japan Email: "xusq@info.human.nagoya-u.ac.jp * b41861a@nucc. cc. nagoya-u. ac.jp Abstract "Computing point analysis" is a new scheme of boundary element analysis lor nonlinear problems without domain discretization. It was pointed out that the accuracy of solution is principally affected by the boundary element discretization employed. Adaptive boundary elements are proposed here for the Pbisson-tvpe nonlinear problem by using the scheme. Local reanalysis method, which measures approximately the sensitivity of the boundary element solution to local mesh changes, is employed for error estimation An /(-version mesh refinement strategy is described and applied to a two-dimensional numerical examp
