What's new in openLISEM 6.1 Beta
Sep 10, 2020
- Warning:
- New dlls, do NOT mix with pre 6.0 versions
- Fixed bug in getting values from Riemann solver
New in openLISEM 6.00 Beta (Sep 8, 2020)
- Extensive rewriting of the code to use parallel processing with openMP
- Changed compilation to MSYS so the newest versions of QT and MINGW are used
- New 2D flow process (very fast), still being tested
New in openLISEM 5.97 (Mar 4, 2020)
- Fixed: flood not well reported in interface
- Fixed: output to file and interface are the same, and lead to a proper mass balance for water
- Fixed: outflow for 0 (all catchment) is now correctly equal or larger than for any outlet separate
- Fixed: channel infiltration is now better/more effective
- Culverts displayed as green dots
- Outlets displayed as white dots and the outlet number is shown when you hover with your mouse on the dot
New in openLISEM 5.95 (Feb 5, 2020)
- Fixed bug in 2D dyn ewave seidment: flow detachment was not working
- Extended options and checked working of sediment traps and grass trips
- 3 flow options: 1) kin wave (no flooding); 2) kin wave and flooding from channels; 3) full dynamic wave
- River vector display can be toggled and line size adjusted
New in openLISEM 5.51 (Sep 11, 2019)
- Added stormdrains: kinematic wave on a subsurface LDD network (lddtile.map) with inlets, diameter (pipe), mannings n, gradient
- Cleaned up everything so that it compiles under QT 5.13, QWT 6.1.4, mingw 73, revised LISEM_EXTERNAL (no fern)
New in openLISEM 5.4 (Jul 3, 2019)
- fixed a bug in SWATRE where the infiltration form SWATRE was not properly subtracted from the surface water layer
- Fixed a bug in Green and Ampt using Psi in the wrong units (cm vs. m) made the calibration for psi also count for SWATRE (this value is multiplied with the inithead maps)
- fixed a small bug where the screenshots were not in the right directory
New in openLISEM 4.96 (Oct 3, 2018)
- Culverts are not included for now (defined in channelmaxq.map), they disrupt the mass balance
- Fixed several bugs in the 2D dynamic wave
- Compaction, crusting and gass strips now also use a different porosity, not only ksat. Therefore infiltration and percolation
- Percolation changes the bottom theta init, and so influences infiltration in principle
- Added theta and percolation to the screen output
New in openLISEM 4.93 (Jan 30, 2018)
- Fixed a bug in boudary conditions dynamic wave sometimes causing too much vertical flow
- Fixed a coding error in erosion slowing down calculations
- Some interface cleanup (Heun in dynamic wave is not useful)
- Multicore remains more unstable than single core, and less accurate
- Possible bug: flood deposition can become negative and positive (only negative allowed)
New in openLISEM 4.92 (Jan 25, 2018)
- fixed a bug for diffusive and kinematic wave introduced in 4.91, in calculation of the flood vomue!
New in openLISEM 4.91 (Jan 19, 2018)
- fixed a bug in the screen output causing negative values of discharge and a large mass balance error.
- Note: when you select dynamic wave flow, the flood height in mm reported is not part of the mass balance, as it is already
- included in overland flow.
New in openLISEM 4.9 (Jan 19, 2018)
- added dynamic wave for overland flow, three numerical solutions now: kinematic (using LDD), diffusive and dynamic (using DEM).
- Flooding is always solved with a dynamic wave, channel flow is always kinematic.
- Random roughness and surface storage slightly changed to avoid bugs in the dynamic wave solution
- Multi CPU Core application for paralklel computing. If this gives problems, select only 1 core.
- small bugfixes
New in openLISEM 3.99 (Jan 19, 2018)
- BugFix: Calibration factor for Cohesion and Aggregate stability (they were reversed)
- BugFix: in Channel Cohesion, soil sohesion was used instead of channel cohesion
- BugFix: cleaned up litter interception, roof interception and effect of raindrums
- BugFix: ensures that screen information, file and map output is all the same
- Added: Fixed bilinear interpolation for sediment, other options give mass balance errors
- Added: EXPERIMENTAL: an empirical factor (1-99) to increase the flow in the direction of the steepest resistance slope for diffuse overland flow.
- Added: calibration factor for channel cohesion
- Added: if the cohesion of slopes or channels is negative, the detachment is assumed to be zero. Deposition will take place
- Added: total interception (roofs, canopy, litter, randrums) to the screen output (in mm)
- Added: the possibility to write GeoTIFF files for the main map outptu. GTiff is not georeferenced). Tif input is also automatically possible (experimental)
