Notes: Boundary approximation solutions using a singular Green function basis have been widely applied to the solution of a variety of linear problems. To avoid the difficulties associated with integration over singularities it is convenient to use sets of non-singular, complete Trefftz functions, and this procedure has been applied recently with success using an indirect formulation. In the paper we observe that direct formulation is here again possible and that for some problems it performs in a superior way.
