766 4326d 05h werner /trunk/src/ adding the rumple index calculation to iland. missing: script binding, ...
time to move the qtscript engine from management to the main model....
 
720 4625d 23h werner /trunk/src/ fixed a problem when trees died in disturbance and the (unupdated) statistics were used (e.g. the LAI for calculating the water cycle). Now for affected resource units, not only the treelists but also the RU-statistics are updated.
implemented a "radiating" mechanism of border cells. If stand-grid-cells (i.e. 10m height grid resolution) are marked as "outside and forest", then the cells "radiate" some influence on the LIF into the project area. Thus, trees on the edge of the project do *not* have properties of trees standing on a stand edge. Currently, the form/amount of this edge-effect is hard coded.
 
718 4631d 06h werner /trunk/src/ implemented effect of out-of-project area lif to border regions; however the result is not as expected... (Tree::readLIF() function).  
714 4639d 23h werner /trunk/src/ continued to work on the wind module. Moreover, we now have two types of "not in project area" pixels;
There were some tries regarding the performance of the wind module. At first for each 10m pixel all trees were selected within the pixel; this proved to be quite time consuming. In the end, these calculations (i.e. select the tallest tree per 10m pixel, and the species of this tree) are done in the beginning (per resource unit). This is about 10 times faster...
 
713 4640d 09h werner /trunk/src/ implemented a way to split the biomass of a dead tree into several pathways (i.e. to soil, to snags, to atmosphere/removal).  
707 4678d 06h werner /trunk/src/ rework of the random numbers in iland.
Now, many (200000) random numbers are precalculated using a given algorithm (there are three or four choices), then the drandom() etc functions read from this array. After some rotations, the numbers are renewed. The point is: this is now reentrant, so the per-thread storage of MTRand objects is obsolete.
 
706 4678d 23h werner /trunk/src/ some performance tests with random number generators. Results so far are not too indicative.  
705 4679d 01h werner /trunk/src/ series of performance tests / modifications.
Using "valgrind" on the linux virtual machine, some performance
measurements were made.
Some candidates for optimization were tested. (1) the applyLIP()
function (about 30% of total run time in runYear()): here several
inlining options were tested; testing the value of the stamp before
using it (in order to omit the other steps) prooved to be slower than
unsing all stamp values.
(2) the random number generator; here the random number generation is
about 5% of the total run time; the commit contains two/three other
variants.
 
697 4687d 01h werner /trunk/ Doxygen documentation revisited.
After re-establishing doxygen documentation (last update: 2009) a lot of smaller/medium documentation fixes.
Documentation is something that could definitely be always improved ;)
 
671 4730d 05h werner /trunk/src/ Necessary changes for GPL licence (i.e. headers in all source files)  
668 4765d 09h werner /trunk/src/ added additional settings for carbon balance of burned trees.
close to version 0.7.0
 
667 4765d 13h werner /trunk/src/ finetuning of fire module (new species parameters, xml file parameters, ...)  
664 4772d 04h werner /trunk/src/ fixes in the fire module  
639 4891d 03h werner / move current content to the "trunk"  
615 4950d 06h werner /src/ removed windows specific _isnan() calls  
608 4956d 11h werner /src/ adding carbon cycle output (and some necessary book keeping code)  
595 4974d 11h werner /src/core/ changed behavior of coarse roots: if biomass exceeds value from allometric relation, the excell biomass is pushed to the soil (avoid piling up of coarse root carbon in the soil)
inlined some biomass functions in species.h.
 
588 4988d 09h werner /src/core/ added carbon-bookkeeping in the regeneration layer.  
579 4991d 01h werner /src/core/ plenty of new/modified functions in the javascript interface of the management class. e.g. randomize(), mean(), sum(), new kill() and manage() functions.  
564 5002d 02h werner /src/ Improvements of the Management API and functionality.
new functionality:
* killSaplings() -> use a "MapGrid" and remove small trees specifically
* properties defining biomass remove fractions during management

Now the tree list of the management object is cleaned up after a management, i.e. successive managements without reloading the tree list are possible.
