#617: r.sim.water crashes on WinGrass
---------------------------+------------------------------------------------
Reporter: hamish | Owner: grass-dev at 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?
