Hi! I am interested in the same question (How to setup a inhomogeneous and anisotropic material?) so let me know if you have any success. At this moment I am trying to understand is it possible to override (or change) anisotropic_averaging.cpp, as far as it describes how to set individual anisotropic chi1inv (void structure_chunk::set_chi1inv) for each point of the grid.
