"Automated grid generation has applications in a wide range of science and engineering. Each field has special needs due to the particular geometries that must be represented by grids or due to the physics equations that must be solved on the grid. Grid generation for geologic applications of fluid flow, heat transport and reactive chemical transport in porous media pose their own difficulties. The physical equations are highly non-linear, material properties of the media such as permeability may vary by orders of magnitude, geologic structures have none of the symmetry of engineered geometries and the domain of interest may span large volumes with phenomenon at small length scales having a substantial influence on the large scale solution. A major hurdle to grid generation is creating grids which maintain the complex material interfaces of a model with many different material types." "There are three steps in process modeling (1)Developing accurate conceptual models inclusive of geologic interpretation, material characterization and construction of a stratigraphic and hydrostratigraphic framework model (2)Building and initializing computational frameworks; grid generation, boundary and initial conditions, (3)Computational physics models of flow and transport."
