## Simulation and Parameter Estimation in Geophysics

An open source python package for simulation and gradient based parameter estimation in geophysical applications.

### Installation

The easiest way to install SimPEG is from PyPI, using pip:

> pip install SimPEG

Read more detailed installations instructions in the documentation.

Get the source code at Github.

### An extensible framework for geophysical inversions

Check out the documentation and the paper for an overview.

### We are developing for all sorts of geophysical applications
