## 1. Overview
|
|
|
The inverse method analysis provides a quantitative estimation of the force network inside a granular media made in a photoelastic material. With such analysis, the contact force's magnitude and orientation can be determined under some assumptions. The main idea of the inverse method is to generate a numerical photoelastic picture that matches the experimental one like illustrated below (the experimental picture comes from [the Matlab implementation of the method](https://github.com/jekollmer/PEGS)).
