SimPEG (Simulation and Parameter Estimation in Geophysics) is a python package for simulation and gradient based parameter estimation in the context of geophysical applications.

The vision is to create a package for finite volume simulation with applications to geophysical imaging and subsurface flow. To enable the understanding of the many different components, this package has the following features:

* modular with respect to the spacial discretization
* is built with the inverse problem in mind
* supports different hyperbolic solvers (Euler, Semi-Lagrangian, Lagrangian)
* supports 2D and 3D problems
