Modeling subsurface phenomena for tetrahedral meshes

SceneGen is a set of tools for creating a subsurface mesh with very little human interaction. The tool set created allows the user to incorporate structured lattice data, typically generated from geo-statistical packages, and make a smoothed boundary representation (b-rep) for each of its material regions. Tools have also been created to take ground surface height-field data and create b-reps for Boolean combination with the geostatistical information. Constructive solid geometry (CSG) techniques are being developed to add subsurface items such as rocks and debris and incorporate them into the model as well. This subsurface system of material boundary regions is then capable of being meshed for finite element simulations. In this way, multiple unstructured tetrahedral meshes may be simultaneously generated on high performance computers.
