Abstract :
The errors involved in the calculation of forces by Maxwell stress summation are examined and a method of improving the accuracy is presented. The method transforms the standard integration into a summation of forces acting on elemental edges in the region of integration after applying a field correction. Three test examples, two of which have analytical solutions are available, are used to show the effectiveness of the method proposed
