focus his work on solving efficiently unbounded, immersed body Poisson and Helmholtz problems. Indeed, the unbounded immersed body problem is widely studied through the literature, however, only a few work has been done regarding efficiency and fast solving using the immersed interface method. His thesis is framed by G. Winckelmans and Ph. Chatelain
