The Trefftz method may be described in terms of an integral equation formulation based on eigenfunction expansions rather than the usual element (BEM) solution method. Using an 'Embedding Integral Equation' approach, the Trefftz method may not only be seen to be related to integral equation methods but it is also seen to be amenable to partitioning, allowing more rapid convergence.

In this paper, the Trefftz method of fundamental solution (FS), called the method of fundamental solution (MFS), is used for biharmonic equations. The bounds of errors are derived for the MFS with Almansi's fundamental solutions (denoted as the MAFS) in bounded simply connected domains. The exponent
The embedding integral equation method is an integral equation formulation for engineering problems similar to but distinct from the well known boundary integral equation method. Both of these formulations may be solved by either element or eigenfunction expansion techniques. The embedding integral
The accuracy of the charge simulation method of calculating electrostatic fields can be improved by optimization techniques that involve the determination of the best location and strength of each individual charge and its image. This paper presents a method that eliminates the optimization of the l
