Full Changelog: v4.0.0...v4.0.1

v4.0.0

Changelog:

Main Kassiopeia development is moved to github! KATRIN internal development for Kassiopeia is a thing of the past as we aim to create a more lively environment for developers and users of Kassiopeia. This is the last time you will see "Update from Kasper develop" as a commit message!

KEMField:

• Replace KSmartPointer with std::shared_ptr
• Show ZH-statistics at the end of computation
• Added new ZH-solver magfield_coil_field_solver

Kassiopeia

• Added DumpMagnetGeometry tool
• Added zonal harmonic terminator ksterm_zh_radius

Kommon

• Remove TBB dependency

Other

• Minor Bug fixes
• Added BunnySimulation as an example for animations with ParaView

Full Changelog: v3.8.2...v4.0.0

v3.8.2

Changelog:

• C++ 17 is now used by default
• Code cleanup & more consistent CMake configuration

Kassiopeia:

• Updated XML example configurations
• New TrackViewer executable for track/geometry visualization from command line
• Some fixes for ROOT < 6.24

KEMField:

• Improved VTK visualization (via KEMVTKViewer class)
  • Now shows mesh quality by default
  • Total surface charge is now also exported in .vtp files
• Fixed work distribution over nodes with OpenCL+MPI
• Various compilation fixes for Linux & MacOS

KGeoBag:

• The GeometryDump executable can now produce GraphViz output for tree visualization

Kommon:

• Restructured the Kommon into independent library targets, with better handling of internal dependencies

v3.8.0

Changelog:

• Complete overhaul of the build system: now uses proper CMake target definitions
• Various fixes to ROOT and VTK visualization
• Code cleanup & improved formatting

Kassiopeia:

• Added simulation examples; now also contains a Python notebook
• Added text file generator (use particle definitions from ASCII file)
• Fixed simulation issues when using "ghost" particle or linear trajectory
• Fixed issue with missing step in output after particle termination
• Restored old ("classic") cosine distribution in generator; added user options: classic vs. molecular

KEMField:

• Update to OpenCL 2.2 headers
• Added sanity checks for electrostatic solvers
• Fixed issue with reading corrupted files (which led to memory leak)
