Comparison of the inverse problem solutions for a 2D damp wall multilayer and nonhomogenous models

Non-destructive methods like EIT tomography can be used to search for the distribution of wall dampness. From a practical point of view the boundary is searched between wall areas considered as dry and damp. For the forward problem solution the boundary element method will be applied. This allows us to use either the multilayer model or a model implementing functionally graded materials. Within the inverse problem solution coefficients for the height and shape of the boundary between the damp and dry model, or distribution coefficients of functional material properties will be searched.
