#617: r.sim.water crashes on WinGrass ---------------------------+------------------------------------------------ Reporter: hamish | Owner: grass-dev@lists.osgeo.org Type: defect | Status: new Priority: normal | Milestone: 6.4.0 Component: Raster | Version: 6.4.0 RCs Resolution: | Keywords: wingrass, r.sim.water Platform: MSWindows XP | Cpu: x86-32 ---------------------------+------------------------------------------------ Comment (by huhabla):
I have hardly tried to find the error using valgrind, but was unsuccessful. Neither the grass6.4 version nor the grass7 version showing any suspicious behavior on 32bit Linux. So i don't know if my changes may have solved the problem, but it would be great, if anybody may compile the latest grass7 version on MacOS or Windows for testing, running the speafish60 example. Helena can you please provide a simple spearfish example for r.sim.sediment, so i can test my changes with this module? BTW: Is it possible to add the water depth in every step to the elevation map and additionally computing the direction derivatives dx and dy to avoid infinite water accumulation in sinks and pits? I suggest this will make the solution of the partial differential equation non linear, but maybe the time steps are already small enough to implement this as an explicit step?
