The geometrical distribution of the fillers has a large impact on the electrical properties of the composites. Many excellent theoretical studies via simulations have already been conducted in order to investigate the relationship between geometry and electrical properties. Most of these studies have however assumed an idealized isotropic orientation of the fillers, and focused on only one variable of geometrical distribution. Therefore, a universal and anisotropic platform of simulation, containing three simulation modules are explored [1]. The simulation modules are: finite element modelling (FEM), percolation threshold modeling (PTM) and electrical networks modelling (ENM). After constantly updating and improving in the past years, the simulation platform performs high degree of flexibility, high degree of automation, high efficiency and high accuracy. Within the platform, all the factors could be controlled as either constant or variable, and a deeper understanding of the relationship between different factors is comprehended. An experimental consideration with multiple levels of variables is carried out, and the synergistic relationship of the variables could be systematic studied. The trend of change in each variable under different environmental settings is clearly displayed and systematically studied by the simulation platform.
