Validation of Measurement Strategies and Anisotropic Models Used in Electrical Reconstructions
We are developing approximations of electrically anisotropic materials for use in novel imaging methods. Our modeling work in COMSOL comprises comparisons of anisotropic and layered models in terms of electrical conductivities measured using different strategies. We tested solution stability in one anisotropic case by varying mesh anisotropy. In our case, good approximations to the true anisotropic solutions were usually found only at extremely fine mesh levels.
