Magnetic field calculations by the boundary element method (BEM) are appropriate to particle optics simulation due to the inherent smoothness of field values, which is a consequence of the integral formulation of the problem. This allows the use of high-order and accurate ray tracing algorithms, as

The present note illustrates a criterion to improve the computational capability of the approaches proposed by Beltrami et al. [Beltrami, G.M., Bargagli, A., Briganti, R., 2003. Gravitational mode calculation of basins discretised by orthogonal curvilinear grids. Ocean Engineering 30, 833-853] for t
A new method for improving the approximations of stress intensity factors computed from pathindependent integrals is developed. The method uses Richardson's extrapolation. Numerical results are given to show the eciency and the stability of the present method. # 1998 John Wiley & Sons, Ltd. KEY WOR
