Version 3.0.0
(September 2019)
Major Release v3.0
General
- Supported operating systems: Linux Ubuntu 16.04 and 18.04, Microsoft Windows 10 - 64bit
- Backend types: CPU, GPU (linux only), OpenMP
- New GUI (Graphic User Interface)
- New simulation workflow: numerical simulation in 3 steps (Setup, Simulation, Results) with separate executables for GUI, setup, results and for each simulation backend, e.g. for CPU, SMP and GPU
- Storage of setup and results files in HDF5 container (*.h5)
- New mesh (element centered, 1st order)
- Same mesh used for hydrodynamics and morphodynamics simulations
- Pre-processing: two procedures to generate a mesh using BASEmesh v1.44 (QGIS plugin)
- Stringdef list and material indices included in the 2dm file
- JSON command files
- Restart and rerun
- Results in xdmf format
- The value at boundary condition is averaged over the stringdef length (hydraulics and morphology)
New Features
- Linked boundary condition with fixed water surface elevation at upstream boundary (zhydrograph_linked) is implemented.
Bug Fixes
- progress bar now displays a simulation progress between 0% and 100% correctly
- results of the flood tracking feature are written to the .xdmf file.
- some results (flow velocity, flow radius) were displayed incorrectly (ParaView) or not displayed at all (QGIS) by viewers. This problem has been fixed by writing these results to an auxiliary file when exporting XDMF files.
- fix in the curvature computation (hydraulics)
Subsystem BASEplane
Hydraulics
- Boundary types: Wall (default), Standard, Linked (new) and Internal (new)
- Riemann Solver: HLLC, with hydrostatic reconstruction based on modified states (Duran et al., 2013)
- Sources with sink behaviours: exact, available and infinity
- Flood tracking
- Safe mode parameter
Morphology
- Bedload transport: HLL-type Approximate Riemann Solver (Soares-Frazão and Zech, 2011) with Godunov-type upwind scheme
- MPM-like and GRASS-like bedload formula
- Boundary conditions: Wall (default), Standard
- Geometrical (default), wetted area or conveyance weighting schemes for inflow boundary conditions ‘sedimentograph’ and ‘transport capacity’.
- Fix bed elevation over regions (index)
