Description

Updates to Simple regularization

  • from pr #807
  • commits by: @fourndo
Summary

Proposed modification to the model gradient measure for Simple and Sparse regularization. Normalized length scales are multiplying cell_weights before averaging to cell faces.

  • Reduces the dependency of the model on cell size changes
  • Still allows for IRLS weights to be mesh independent
  • Default alpha's remain at 1 (takes care of length scales internally)

Before

After

Additional Notes This pr also removed 2 VRM examples and the 1D MT example as they were failing. Issues #812, #814 document the issues, and pr's #813 and #815 have been started to resolve those issues.

Updates to Utils.plot2Ddata
  • from pr #808
  • commits from: @thast
summary

add shading options in utils.plot2Ddata

Minor updates:
  • small fix in the calling of mkvc in the regularization mesh (from #810, commits from @thast)
  • update dependencies in the setup.py to remove indirect ones (from #188, commits from @lheagy)
