Abstract
The first author has previously developed a third degree polynomial co ordinate transformation which improves the accuracy of numerical quadr ature schemes typical of boundary element implementations. This transf ormation is now extended to include additional integrand variations an d kernels of order ln(1/r),1/r,1/r2 and 1/r3 are discussed. The optimi zed parameter which governs the transformation is presented in tabular form for several source to element minimum distances.
