Description

Simulation and inversion of time domain IP

  • from pr: #590
  • commits from: @sgkang, @fourndo, @micmitch
  • review from: @lheagu
Implementation:
  1. Use stretched exponential (chargeability, time constant, frequency dependency) for parameterization

  2. Tested 2D and 3D SIP problems

  3. Deprecate Multiregularization and use combo objective function, so pulled ref/objectivefunctions branch - This is for inverting multiple parameters. Thanks @lheagy and @fourndo for combo objective functions, and @rowanc1 for wire implementation!

  4. Implement storeJ option for both IP and SIP problems (2D and 3D), which boost up speed for relatively small problems.

Example: True model

Recovered model
