A new method for estimating the nonuniform distribution of moisture content in solids is developed using inverse analysis. Since this inverse problem is ill-conditioned, direct application of the conventional method for solving inverse problems results in an oscillatory solution. To avoid this difficulty, the nature of the material, that the distribution of moisture content is governed by the diffusion equation, is taken into account, and the number of unknown parameters is reduced. The multiple-domain boundary element method is employed for analyzing the electric field within the solid. Some example problems are solved using this method in order to demonstrate the accuracy of the estimation.
