SimPEG: Simulation and Parameter Estimation in Geophysics_News & Media

Why About Contact Contribute Simulation and Parameter Estimation in Geophysics An open source python package for simulation and gradient based parameter estimation in geophysical applications. Geophysical Methods Contribute to a growing community of geoscientists building an open foundation for geophysics. SimPEG provides a collection of geophysical simulation and inversion tools that are built in a consistent framework. Gravity Magnetics Direct current resistivity Induced polarization Electromagnetics Time domain Frequency domain Natural source (e.g. Magnetotellurics) Viscous remanent magnetization Richards Equation Forward Simulations Finite volume tools that work across many different discretizations and dimensions. Simulate your geophysical method in 1D, 2D, 2.5D, 3D and through time. Refine around areas of interest using an OcTree. Tensor mesh OcTree mesh QuadTree mesh Logicaly rectangular mesh Cylindrical mesh Access to derivatives Plotting utilities VTK export Inversion Components The SimPEG inversion framework is modular, allowing you to explore, experiment and iterate over a variety of approaches to the inverse problem. Optimization Regularization Data misfits Parametric models Joint inversions 🚀 Get Started 🚀 The easiest way to install SimPEG is from PyPI, using pip. If you get stuck or have no idea what a pip is, jump on Slack or Discourse to ask the community a question!!
