implementing the interaction between bark beetle and wind disturbances;
introduced new flags to mark the reason why trees died when they do die, and a mechanism that allows disturbance modules to being notified when trees die. This involved the creation of a new "DisturbanceInterface". |

Fixed a snapshot issue.
Now the water-content and the snow-pack are also stored in the snapshot.
statistics are forced to be re-created. |

changed the sanity check on the HD value of the increment (lower bound was 20 which produced tons of log output). |

Steps to build iLand with Qt 5 and with MSVC compiler and 64 bit.

removed also a couple of warnings that were thrown by the MSVC compiler. |

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. |

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... |

implemented a way to split the biomass of a dead tree into several pathways (i.e. to soil, to snags, to atmosphere/removal). |

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 The point is: this is now reentrant, so the per-thread storage of MTRand objects is obsolete. |

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. |
