Full Changelog

Breaking changes

  • BoutMesh::GlobalNy now counts points from all y-boundaries. Previously it only counted points from the boundaries at the upper and lower edges of the logical grid, even if there was another boundary in the grid. #1829
  • invert_laplace free function removed #1834
  • Most factories and create methods standardised. Run bin/bout-v5-factory-upgrader.py on your physics models to update them #1842 #2087
  • We now use fmt for all our string formatting, instead of the printf-style formatting. This affects calls to Output, BoutException/ParseException, DataFile, OptionsReader, and MsgStack/TRACE. Run bin/bout-v5-format-upgrader.py on your physics models to update them. #1847
  • The option laplacexy:y_bndry_dirichlet has been deprecated. Use laplacexy:y_bndry=dirichlet instead. #1789
  • The variable BOUT_VERSION, and the macros REVISION, BOUT_VERSION_STRING and BOUT_VERSION_DOUBLE have been replaced with constexpr variables in the bout::version namespace. REVISION is found in include/bout/revision.hxx, while the rest are in include/bout/version.hxx. Both files are generated at configure time. Run bin/bout-v5-macro-upgrader.py to update. #1920
  • The MUMPS Laplacian inversion wrapper has been removed. It is still possible to use MUMPS for Laplacian inversions through the PETSc wrapper. #2018
  • The using namespace bout::globals statement has been removed from physics_model.hxx, and PhysicsModel has gained public mesh and dump members. Custom mains, free functions and legacy models will need to be updated to either use bout::globals::mesh or Field::getMesh() in free functions. #2042
  • The LaplaceShoot Laplacian implementation was removed. There are very few cases, if any, where this implementation actually works. #2177
  • PhysicsModel expects the options datadir and dump_format to have been set; this is only a problem if you don't call BoutInitialise. #2062
  • dz is now a Field2D, and Coordinates::zlength() also returns a Field2D. In most cases, wrapping these in a call to getUniform in order to get a BoutReal will do the correct thing. If checks are enabled, getUniform will throw an exception if its argument is not uniform (that is, that all values are identical). #2025
  • The parallel boundaries BNDRY_PAR_FWD and BNDRY_PAR_BKWD have been expanded to distinguish between the inner and outer boundaries in x; the enums have been replaced with BNDRY_PAR_*_XIN, and BNDRY_PAR_*_XOUT for both FWD and BKWD. #2025
  • Support for reading/writing HDF5 files has been removed ahead of completely refactoring the I/O
  • Support for reading/writing HDF5 files has been removed ahead of completely refactoring the I/O systems. #2208
  • Removed the Karniadakis time solver. Other choices for split-operator schemes are: splitrk (built-in), imexbdf2 (requires PETSc), and arkode (requires SUNDIALS) #2241
  • Conversion of Option to bool is now stricter. Previously, only tested (case-insensitively) if first character was 'n', 'f', '0', 'y', 't', or '1'. Now only allow (still case-insensitively but checking full strings) 'n', 'no', 'f', 'false', '0', 'y', 'yes', 't', 'true', or '1'. #2282
  • Having any unused options remaining after the first call to the physics model rhs is now an error. Set input:error_on_unused_options = false for old behaviour #2210
  • Input options are now case sensitive. Run bin/bout-v5-input-file-upgrader.py to automatically fix the most common library options #2210
  • Input options are now required to be either a section or a value, and not both. This requires renaming the restart section to restart_files. bin/bout-v5-input-file-upgrader.py can automatically make this change. #2277
  • Options are now only implicitly-castable to types stored in the internal variant. Other types now require a call to Options::as<T>() #2341
  • The Laplacian inversion solver LaplacePDD ("pdd") has been removed. This implementation had some quite significant drawbacks that made it not terribly useful in practice #3566
