468 5017d 10h werner /src/ starting the implementation of the snag dynamics submodule.
New class: Snag
added Snag to ResourceUnitSpecies
added links to Snag in Tree
 
465 5017d 16h werner /src/core/ fixed bug in TACA model calculating fEnvYr.  
463 5018d 04h werner /src/core/ To handle errors in diameter estimation for small trees, an iterative algorithm is used if the "final residual" (between NPP based stem biomass increment and realized stem increment) is > 1kg.  
460 5018d 07h werner /src/ changed label in regeneration debug output,
added minimum height of 4m as requirement for seed production.
 
445 5117d 15h werner /src/core/ added database species parameters for seed dispersal, fixed a bug with random generator in StandLoader, change maturity criterion for seed production to age instead of height.  
444 5119d 11h werner /src/core/ added a "randomGenerator" - function to the resource unit -> this should be used when fetching random numbers from within functions that are executed in a multi-threaded way. You could also use GlobalSettings::instance()->randomGenerator().  
428 5148d 12h werner /src/ added linearization for some expressions (e.g. light response), and a global switch to enabled/disable the linerization using one static boolean (triggered by a iland setting)  
426 5149d 12h werner /src/core/ added the LRImodifier key, which is used to scale down the LRI of small trees that are below very high trees.  
410 5151d 04h werner / height grid: removed 5m from neighboring height grid pixels
new version of fonstudio (log output again to log window)
 
407 5151d 13h werner /src/ modified the painting of trees (use now the crown radius)
tried to fix the database lock error when reloading the model (not solved: but: no problem when model was executed for at least one year...)
 
406 5151d 16h werner /src/core/ set ground height of height grid to 4m (model.cpp)
modified height-grid-apply (non-torus) so that height-grid pixels get max()-ed if the reader stamp reaches into the neighbor pixels (i.e. the crown reaches the neighbor 10m pixel)
 
403 5154d 08h werner /src/ Tree::applyLIP(): fixed bug with the indices
applyLIP/readLIF: changed way of applying/reading LIPs. Version where hdom is only set at the focal height pixel.
model.h/model.cpp: tried a version with a init-value for height of height grid
 
401 5157d 04h werner / starting from a change in the LIP-pattern and the LIP-application a grand tour through followed.
StampContainer has now a static grid that holds distances to the stamp-center. This is used by the tree when applying a stamp.cpp
minor changes necessary due to the switch to Qt 4.6
 
399 5157d 16h werner /src/core/ cleanup at applyLIP() in tree.cpp  
397 5172d 16h werner /src/core/ thanks to ruperts sharp eyes we found a bug in the torus implementation of readLIF_torus(). Basically, the wrong pixels were evaluated. This became apparent in the HJA with very structured stands.
Another possible flaw (not sure whether this actually caused errors) was found in the attachment of reader stamps.
 
393 5175d 14h werner /src/ fixed a bug in StampContainer when loading trees with invalid hd-ratio (too low trees).
fixed a bug that caused a crash when seed dispersal was disabled.
added return values for stand init routines (also those that accessed by scripting) and cleaned up the documentation.
 
389 5178d 02h werner /src/ fixed small glitches with single tree initialization (species name at last position); changes to management routines.  
388 5178d 04h werner /src/core/ remodified the age calculation. Now the age is estimated based on the current height relative to h_max. The aging-calculation itself is no longer changed by that.  
387 5178d 04h werner /src/ integrating seed dispersal into the model
moved global constants for grid sizes into globalsettings.h
 
381 5178d 15h werner /src/core/ appropriate handling of tree age during initialization.
if no age is provided in the input file only the tree height is used for the aging calculation. The tree "age" in that case reflects only the number of years since initialization.
 
376 5187d 14h werner /src/ calculation of an average value for aging at resource unit level.
added variable 'aging' for resource units.
changed comments.
 
326 5325d 10h werner /src/core/ corrected LRI for HD-calculation (tracker#11)  
321 5325d 12h werner /src/ * check for NaN in readLIF_torus() (Tree).
* dump() function in Stamp
* removed compiler warnings
 
308 5333d 13h werner /src/ changed stress mortality (tracker#4)  
303 5335d 11h werner /src/ tree output (tracker#7) added position  
299 5345d 14h werner /src/ fixed bug with disabled debug outputs
added modified LRI to NPP-debug output
new species parameter "probStressYears".
documentation (wiki-links)
 
298 5347d 07h werner /src/core/ comments  
297 5362d 20h werner /src/core/ reserve size in tree partitioning.  
295 5363d 20h werner /src/core/ "torus"-mode of light calculations for multiple simulated units. Each RU "wraps" its influence around the edges of the respective resource unit. This works now for more RUs simultaneously.  
285 5369d 18h werner /src/core/ loading of the landscape. added "areaMask.imageFile" to "world" in xml file. This loads a image mask that establishes area that are inside and outside the project area respectively.  
279 5370d 19h werner /src/ stressIndex in TreeOut, deactivated DBGMODE makros  
278 5370d 19h werner /src/ Management output. Added a statisticsMgmt() for ResourceUnitSpecies. Complicated to get the order right.  
277 5371d 01h werner /src/ added "Gesamtwuchsleistung" i.e. total growth.  
276 5373d 04h werner /src/ added explicit fine root compartment in tree. Changed partitioning, the calculation of the stress index, follow-up change in several outputs.  
274 5373d 06h werner /src/ lightResponseClasses (changed in SpeciesSet, Species and Tree)  
271 5373d 19h werner /src/ watercycle now counts evaporation from crown separately, fixed bookkeeping error in watercycle debug output.  
265 5374d 19h werner /src/ tried to run iLand again for larger area, and got into concurrency-issues. Reasons:
* debug-messages: are now buffered in a string list and not instantly sent to the QTextEdit
* Expressions: lightResponse-formula: accessed concurrently by several threads; now there are thread-safe versions (executeLocked() and calculateLocked()) that use a QMutexLocker to properly serialize the execution flow.
 
264 5375d 03h werner /src/ TreeOut output (including filtering)  
262 5375d 04h werner /src/ added output for dead trees (StandDeadOut)  
261 5375d 06h werner /src/ * added NPP aboveground to stats
* some update in comments
