Some benchmark problems and basic ideas for the accuracy of conventional and fast boundary element method

摘要

BEM is an analytical-numerical combined method,high accuracy,easy to deal with the singularityproblems are its inherent advantages.In recent years through the introduction of fastalgorithm,the efficiency of the fast BEM is significantly improved,in solving large-scale problemsalso shows wide application prospect.However,in order to give full play to the advantage of itshigh accuracy,the algorithm to all aspects of the error to be effectively controlled,otherwise,theaccuracy of the computation is difficult to guarantee.
