SimPEG is software for simulation and gradient-based parameter estimation in geophysical applications. It provides a modular framework for constructing forward simulations and solving inverse problems involving subsurface physical properties.

The software is built around finite-volume numerical methods and supports geophysical imaging, electromagnetics, resistivity, induced polarization, potential-field methods and hydrogeological problems. Its modular design lets users combine different meshes, physical simulations, optimization routines and regularization strategies for problems ranging from small teaching examples to large-scale inversions.

This is free and open source software.

• Provide modular spatial discretization, optimization and geophysical problem components.
• Build forward simulations with inverse problems in mind.
• Model geophysical and hydrogeological problems.
• Support one-dimensional, two-dimensional and three-dimensional problems.
• Perform large-scale geophysical inversions.
