WebThe problem, thus posed, differs from typical boundary value problems which basically deal with the solution of a potential function. The tool design problem seeks for boundary geometry instead of potential distribution, and is known as an inverse boundary value problem or free boundary problem of the Laplace’s equation and it indicates how ... Webat aand b. This boundary condition arises physically for example if we study the shape of a rope which is xed at two points aand b. Choosing 1 = 2 = 0 and 1 = 2 = 1 we obtain y0(a) = y0(b) = 0. The general conditions we impose at aand binvolve both yand y0. Unlike initial value problems, boundary value problems do not always have solutions,
