376 5283d 04h werner /src/ calculation of an average value for aging at resource unit level.
added variable 'aging' for resource units.
changed comments.		  
370 5290d 02h werner /src/ * expansion of the logwindow on the mainwindow
* bug with multi threading: serialization using QMutexLocker when attempting to write/print the debug outputs.
* enabled painting of the visuals in modelcontroller.cpp (re-enabled??)
* changed the threshold for multi threading to 6 resource-units
* optimized StatData-class to avoid unnecessary calculations of percentiles
* several comments		  
369 5290d 05h werner /src/ * multithreading for 3pg production (crashes)
* do 3PG calculation only if this RU has some leafarea of a species (added clear() functions)
* added GUI-accessible speciesindex-variable for trees		  
367 5290d 06h werner /src/core/ changes in the watercycle.
see http://iland.boku.ac.at/tiki-view_tracker_item.php?itemId=30
the calculation of the effect on the canopy conductance is changed. Now, the combined effects of soil water and vpd response together modify the canopy conductance. In order to do this some structural changes have been necessary. Note: now the response values for vpd and soil water are calculated two times.		  
331 5420d 17h werner / changed order in which statistics are calculated: statistics of species and RUs are now cleared immediately before they are refilled (during the growth of individual trees). Now steps between (e.g. water-cycle) can access valid statistics (that are essentially the state of the end of the last year)  
298 5442d 21h werner /src/core/ comments  
287 5463d 13h werner /src/ Tree initialization (random variant). works almost...  
281 5465d 12h werner /src/ setup of the world - remodeled the init-routine in Model, changed the init of stands (also some xml-keys). added a storage for variables local to rseource units (e.g. nitrogenAvailable).  
280 5465d 19h werner /src/ Creation of the "Environment" class (loading of the "world" into iLand).
- added setter-functions to XmlHelper
- added auxiliary functions to CSVFile
- smaller changes to a bunch of other files.		  
278 5466d 10h werner /src/ Management output. Added a statisticsMgmt() for ResourceUnitSpecies. Complicated to get the order right.  
277 5466d 15h werner /src/ added "Gesamtwuchsleistung" i.e. total growth.  
265 5470d 09h 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.		  
262 5470d 19h werner /src/ added output for dead trees (StandDeadOut)  
257 5471d 18h werner /src/ added production based (tree) statistics.
StandOut after tree initialization.
some documentation polishing.		  
251 5472d 16h werner /src/ Light-Redistribution: Changed again (12.10.2009). LRI of trees are now modified with a modifier based on stockedarea*beerLambert-fraction (pPar). The modified LRI is then used to calculate a light response. The light response * leafarea eventually acts as the share of GPP assigned to a particular tree.  
241 5476d 15h werner /src/core/ watercycle within the model sequence.  
240 5476d 17h werner /src/ water cycle yields first results.
implemented a "createStandStatistics()" function, that calculates stocked areas, and statistics after initialization and before the actual model run.		  
231 5478d 07h werner /src/ 3pg model, strange behavior of database. Modified the transaction logic (really important for SQLite), but still shows odd behavior.  
230 5478d 10h werner /src/ 3PG work out  
229 5478d 12h werner /src/ 3pg model. fixed a problem with the setup of ResourceUnitSpecies (a classic: a pointer to a vector, which is still growing... grrrrr.... it took hours to find)
