v1.6.0

pyGIMLi v1.6.0

This release brings a new structurally coupled cooperative inversion (SCCI) framework, matrix-free Jacobians based on forward operators, first-class support for complex matrices, a substantially reworked user guide, and numerous fixes across the physics managers and build system.

Highlights

• Structurally coupled cooperative inversion (SCCI) framework, including a drawCWeight helper and a worked petrophysical joint-inversion example.
• Matrix-free / implicit Jacobian built directly from a forward operator via fop.Sx(x) and fop.STy(y).
• Complex-valued matrix support: new complex2RealMatrix (represents a complex matrix as a doubled real one) plus first steps toward complex mass/stiffness matrices.
• Reworked user guide: new "getting started" and "how-to-continue" sections, expanded inversion and FE-modelling guides, and a rewritten chapter on unstructured meshes (#881).
• Interactive tutorials are now runnable in the browser via Binder integration (#962).

New features & enhancements

• SCCI inversion framework with drawCWeight and arsinh transformation.
• Implicit Jacobian matrix based on a forward operator (fop.Sx/fop.STy).
• complex2RealMatrix and initial complex mass/stiffness matrix support.
• Error propagation based on absolute errors (groundwork in the inversion frameworks).
• physics.ves.simulate — VES forward simulation without instantiating a manager.
• pg.viewer.mpl.showModel1D as a 1D counterpart to showMesh/showModel.
• TravelTimeManager.showMisfit().
• MagManager improvements: better data-fit display, exportLocations, improved initialization.
• depthWeighting keyword can now also be passed as a depth value.
• Pass kwargs through when showing a data container.
• createSphere mesh primitive (#908) and error handling for time-lapse data (#889).

Bug fixes

• Fixed wrong data unit when reading SIP Fuchs III files.
• Fixed wrong numbers for the forward-operator-based matrix.
• Removed the erroneous absolute value in the chargeability forward computation.
• Fixed boundary limits and backend handling in 3D (PyVista) visualization (related to #925).
• Fixed problems when combining DEMs.
• Fixed an error in the inversion class and waitOnExit for the TkAgg backend.
• Removed deprecated pkg_resources import.
• Properly exit on test failure when exitonerror=True (#879).

Documentation

• Reworked unstructured-meshes section (#881) and added missing docstrings (#955).
• Improved data-container, modelling/FE, and inversion guides; support for custom LaTeX macros.
• Added Schiffler (2025) citation and a paper carousel; "other software built with pyGIMLi" page (#933).
