- Abstract
In this paper, we consider an inverse problem associated with the Laplace's equation of determining the robin coefficient of some specimen material by performing measurements on some part of the boundary. This problem leads to the resolution of a data completion problem to determine the unknown Dirichlet and Neumann conditions on the inaccessible part of the boundary. We propose a variant of an iterative algorithm that perform the standard one to identify the parameter. The algorithm are implemented using the finite element method. The numerical results is performed in the case of a tube 2D represented by an annular domain and irregular square domain showing the effectiveness and the robustness of the proposed algorithm.
