    Harmonic and biharmonic boundary value problems (BVP) arising in physical situations in fluid mechanics are, in general, intractable by analytic techniques. In the last decade there has been a rapid increase in the application of integral equation techniques for the numerical solution of such problems .

Our method works on un-structured polygonal meshes, provides arbitrary approximation order and does not require any global C0 regularity for the numerical solution. The.
