 The .geo files produced by Frackit lead to three-dimensional meshes that are aligned
 with the fracture geometries such that the element faces coincide with the fractures,
 which can be directly plugged into the [DuMuX][0] module for discrete fracture-matrix

+* Kernel for fracture network characterization (e.g. connectivity)
+* Capabilities for translation of fracture networks into graphs, allowing for efficient characterization of the network based on its graph representation.
