文摘This paper implements an improved isoparametric transformation from FEM to BEM, which maps side nodes from global to local coordinate system with the same relative positions along the sides they reside in. An example shows this method can provide a reduction in error of up to 3-4 orders of magnitude compared with the standard transformation when side nodal placements are general.
