Simulation and Parameter Estimation in Geophysics
*************************************************

SimPEG is a python package for simulation and gradient
based parameter estimation in the context of geoscience applications.

The vision is to create a package for finite volume simulation and parameter estimation with
applications to geophysical imaging and subsurface flow. To enable
these goals, this package has the following features:

- is modular with respect to discretization, physics, optimization, and regularization
- is built with the (large-scale) inverse problem in mind
- provides a framework for geophysical and hydrogeologic problems
- supports 1D, 2D and 3D problems
