Simulation and Parameter Estimation in Geophysics - 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, optimization routine, and geophysical problem
• built with the inverse problem in mind
• provides a framework for geophysical and hydrogeologic problems
• supports 1D, 2D and 3D problems
• designed for large-scale inversions

You are welcome to join forum and engage with people who use and develop SimPEG at: http://simpeg.discourse.group/.

Weekly meetings are open to all. They are generally held on Tuesdays at 10:30am PDT. Please see the calendar (GCAL <https://calendar.google.com/calendar/b/0?cid=ZHVhamYzMWlibThycWdkZXM5NTdoYXV2MnNAZ3JvdXAuY2FsZW5kYXIuZ29vZ2xlLmNvbQ>, ICAL <https://calendar.google.com/calendar/ical/duajf31ibm8rqgdes957hauv2s%40group.calendar.google.com/public/basic.ics>) for information on the next meeting.
