Changes in development

Major changes

  • Parallel and asynchronous output writing (#14).
  • Added Icepack sea ice thermodynamics (Zampieri et al., 2021) #70
  • Added backscatter parameterisation (Juricke et al., 2019) #64
  • Initial version of cavities #48, and its improvement #110
  • New defaults in the namelists and a system to create setups from yaml files (#55). Most prominent changes are: Partial cells, zstar and unrotated mesh are now default options, JRA55-do is default forcing.
  • New license (LGPL), as requested by some partners, so FESOM2 can be used as a library by comertial software #74
  • Add an option to smooth tracer (smooth_bh_tra), which is nessesary for very high resolution setups #81
  • Fix partial cells to work more stable in high resolution setups #27

Minor changes

  • Print compile time git SHA at runtime (#13) to undetify version the model was compiled with.
  • More information in netCDF output (#18 #31 #33). Provide some info on model version and setup.
  • Fix bug with partitioner, that sometimes lead to wrong size of triangles #20
  • Add several extra parameters to the sea ice namelist (#34)
  • Introduce MAX_PATH length, to remove limit on the paths #65
  • Ice deformation tensor is stored as an array (on elements) and can bу written out (4cfe296)
  • Remove old METIS4 (66b0b74)
  • Add cray ftn compiler support (#89)
  • Fix coupled (to OpenIFS) thermodynamics where water instead of snow density was used for heat capacity (#93)
  • Fix PPM bug #117
  • Add density / buoyancy flux as output variable #116
