Version 3pre

(April 2019)

Pre-Release v3.0

General

  • Supported operating systems: Linux Ubuntu 16.04 and 18.04
  • 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 (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)

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)
