WebGreen’s function of the problem to compute its numerical solution. However, Green’s functions are only known in a limited number of cases, often under the form of complex analytical expressions. In this article, a new method is proposed to calculate Green’s functions for any linear homogeneous medium from a simple finite element model. WebThe Green’s function for this example is identical to the last example because a Green’s function is defined as the solution to the homogenous problem ∇ 2 u = 0 and both of these examples have the same homogeneous problem.
