Brief description
FracG is a command line tool for analysing fault/fracture networks. The input is provided as line-vector data in shapefile format. Analyses performed by FracG include:- Models of fault length distribution and principal orientations
- Statistical parameters including scan line analysis
- Box-counting to obtain fractal dimension
- Maps of fault density, intensity, distance to faults
- Classification of faults (orientation, intersection numbers)
- Construction of a georeferenced graph
Graph algorithms applied to the georeferenced graph:
- Betweenness Centrality
- Minimum Spanning tree
- Shortest path
- Maximum Flow
Analysis can optionally be extended by including raster data (e.g. DEM):
- Extraction of raster values along faults
- Augmenting the georeferenced graph by using raster data as edge and vertex weights
FracG can also generate 2D conforming meshes of the faults and surrounding rock, suitable for finite element simulations.
Lineage
