Version 2.6.x

(March 2016)

Minor Release v2.6

General

New Features

  • New Windows installers for users with and without admin permission
  • New handling of errors and warnings 
    • writing two files: run.log with log-info and run.err with all warnings and errors
    • the same philosophy is applied in the gui: two tabs, one for info, the other for warnings/errors
    • new log levels: (1) Error, (2) Warning, (3) Info, (4) Debug
  • Open the whole block-tree with command in GUI menu bar (expand all, ctrl+A)

Bugfixes

  • No segmentation fault if user requests to stop simulation AND simulation has already finished

Subsystem BASEparse

New Features

  • New FORMULA block in BEDLOAD block (1D and 2D)
  • Renamed tag 'bedload_transport' to 'bedload_formula' inside FORMULA block
  • New DIRECTION block in BEDLOAD block (2D), with new feature curvature_effect_static (option lateral_bed_slope replaces former tag lateral_transport in PARAMETER block)
  • Deleted obsolete and misleading tag 'output_time_step' in OUTPUT block (2D)

Attention: The changes of the command file structure are not backwards compatible! Input files for v2.5 will not work with v2.6 and vice versa. We recommend all users to update to version 2.6.

Subsystem BASEplane

New Features

  • Index based definition of river curvature (radius) to simulate curvature effect on
    sediment transport (change of bedload direction) in new DIRECTION block

Bug-fixes

  • Review of HLL and HLLC Riemann solvers
  • Fixed coupling sediment boundary 'coupling_IODown'
  • Tag 'use_cell_averaged_bedload_flux' in PARAMETER block in BEDLOAD block is
    set to 'off' per default
  • factor_reference_height set to 0.1 by default (not 1.0) for suspended load
  • Flux orientation in wall flux boundary

System Manuals

  • New Tutorial Post-Processing of 2D Simulation Results
  • Updated Tutorial Pre-Processing in QGIS with BASEmesh
  • Additions and corrections in System Manual
  • Review of HLL and HLLC testcases
