v3.7.2

Bugfix release to v3.7.1

v3.7.1

Bugfix release to v3.7.0

v3.7.0

Changelog:

• Major update of Kassiopeia and KEMField (see below!)
• Code reorganization and bug fixes.
• Improvements on build process and usability.
• Added Unit tests. Set BUILD_UNIT_TESTS=ON to enable.
• Applied code formatting through clang-format (see the provided .clang_format file.)

All executables now have better handling of commandline arguments. Use Kassiopeia <config.xml> -r param1=value1 param2=value2 or Kassiopeia <config.xml> --param1=value1 --param2=value2. This also work in geometry painters and field calculators.

A Dockerfile is now available here or through the DockerHub.

Kassiopeia

• Updated H2O angular cross-section.
• Changed "ghost" particle mass to non-zero value.
• Improved handling of GSL errors.

• Added neutron beta decay recoil energy generator: #17.
• Added vtk_generator_painter.
• Added option for eV-units in gen_value_boltzmann.
• Added simple field calculator tools.
• Added particle index field.
• Added output fields for term_drift and int_scattering calculators.
• Fixed control_length for magnetic particles.
• Fixed wrong value of discrete_energy_loss output field.
• Build & bug fixes.

KEMField

• Miniz upgrade to v2.1: #22 (used when KEMFIELD_USE_ZLIB=OFF.)
• Added options/bindings for fieldmap calculators and zonal harmonic solver.
• Added local origin to constant E/B fields (to define potential.)

• Added GSL error handler class.
• Added independent Maths and Binning libraries.
• Improved XML initializer interface for commandline arguments.
  • Added --param=value option handling.
  • Added -v / -q verbosity options.
