Abstract :
An approximate closed-form expression corresponding to the energy functional in an infinite exterior region satisfying Laplace´s equation is derived for use with the finite-element method. This expression simplifies the treatment of exterior-field problems in numerical calculations. The expression is given in terms of a few numerical matrices and logarithmic functions.
