0000825: Slow simulation if Regeneration Model Type is set to database

Mon, 19 Oct 2026 10:47:17 +0200

A RegWise simulation was very slow when Regeneration Model Type = Database. It seemed to be the only setting that impacted the run time.

0000823: Volume cut all species is 0 while extracted volume > 0

Tue, 29 Sep 2026 08:52:45 +0200

For some treatments that comes from treatment proposals the VolumeCutTotal is expected to be equal or larger than the HarvestVolumeM3FubTotal, but the volume cut is 0 while HarvestVolumeM3FubTotal is large.

0000815: Add the field IsThinned to stand register

Thu, 17 Sep 2026 08:34:17 +0200

Currently a user can add the date for the last thinning in the field LastThinningDate. However, if a thinning has NOT been made the user can't stop the system from assuming a thinning HAS been made. See GetNumberOfThinnings(...) in ThinningGuidebase.cs

Add a new field like "Thinned"/"IsThinned" to the stand register. Do not forget to update the Excel template and the wiki.

If LastThinningData is set: the field IsThinned can/should be ignored and LastThinningData should be used.
If LastThinningDate is missing and IsThinned is false or missing: Heureka should not infer that there is been thinnings.
If LastThinningDate is missing and IsThinned is true: Heureka will assume 1 thinning has been made

0000820: TreeRegistrationControl dialog does not display correctly in Swedish

Mon, 08 Jun 2026 13:07:09 +0200

The bottom panel renders behind the tree list for Swedish language.

0000821: Enforced thinning grade critieria not used

Thu, 04 Jun 2026 14:35:23 +0200

Enforced thinning grade critieria is only evaluated if the ThinningApplicable status is TooHighForFirstThinning.

0000816: Fix inference of historical thinnings

Thu, 28 May 2026 13:34:07 +0200

Now the algoritm for infering if thinnings has been done but are missing from for example LastThinningData in the stand register uses the current period. That means the number of infered periods can change over time. It would make sense to only evaluate the forest state in period 0 and then use that result.

0000817: Missing thinnings with period midpoint

Fri, 15 May 2026 14:54:11 +0200

If the dominant height is too high for a young stand first thinning and no thinning was found and a thinning should be enforced, the wrong thinning period is calculated if period midpoint is used and the thinning can not be applied

0000798: Report Template selections are reset between sessions

Wed, 06 May 2026 10:33:28 +0200

Selections should remain between sessions and be specific to the project.
Should be implemented similarly to how result variables are handled.

0000807: The result variables for growth data are not correct for Checkboard management

Wed, 06 May 2026 10:32:26 +0200

The result variables for growth data (CAI) are miscalculated due to the assumption that one year can not have multiple harvests.

0000808: Incorrect version handling of final felling and thinning delay values

Wed, 06 May 2026 10:31:38 +0200

Final felling and thinning delay control table variables' units were changed from period to years.
However, the conversion of values between version were done incorrectly, making some values not convert correctly.
All values should now convert correctly from period to years.

0000814: Optimization results in column mode not updating

Fri, 24 Apr 2026 12:36:22 +0200

When looking at optimization results in column mode the view is not updated when number of periods is changed in the numericupdown.

Hello Jonatan,

when i am trying to load all treatment units from a simulation using Regwise i am getting this error message. "Damage risk data potential basal area already belongs to this data table". the treatment units is not loading and i am not able to click on "select variables". but i can see simulation output from single treatment unit and i can select the output variables for one treatment unit. any idea on what is causing this problem?

--- Exception ---
System.Data.DuplicateNameException: A column named 'DamageRiskData Root Rot Potential Basal Area' already belongs to this DataTable.

0000812: Change: Removed Cudafy from HabitatModel

Fri, 20 Feb 2026 13:40:15 +0100

The outdated package Cudafy was used when evaluating Habitat models. The package is now removed. It should not have any side effects.

0000806: Wrong coefficients in tree age functions

Wrong coeffecients are used for rich and poor in the method TreeAgeWithoutStandAge

0000805: Blir ingen gallring när Thinning Delay Max sätts till 0

Fri, 19 Dec 2025 16:10:13 +0100

För beståndet sker gallring i period 2 och 3 och slutavverkning i period 6 om Thinning Period Delay Max = 2.
Om Thinning Period Delay Max sätt till 1 blir det gallring i period 2.
Om Thinning Period Delay Max sätts till 0 blir den ingen gallring alls.

0000801: Önskad funktionalitet. TIllåt specifika trädslag i UserDefined-result

Tue, 25 Nov 2025 09:12:25 +0100

Jag vill kunna redovisa volym RASE (Rönn, asp, sälg, ek). Ek och asp finns som egna trädslagsgrupper, men sälg och ränn ingår i OtherBroadleaveas.
En lösning vore att tillåta att ett User Result definierar för specifikt trädslag (Species) och inte bara trädslagsgrupp. Undrar om inte denna funktionalitet har funnits tidigare?

0000799: TPG missar gallringar?

Thu, 20 Nov 2025 15:37:27 +0100

Bifogar exempel där det borde gallras i period 1 när man kör med periodmitt, men av okänd anledning görs det inte.
Grundytan är hög och enligt bakomliggade gallringsmall (SKS) borde det vara hög gallringsprioritet.
Relativa åldern är inte för hög och inte heller övre höjd (dominant height).

0000796: The order of map layers makes a difference when calculating intersections in the Initial State --> Map view

Wed, 12 Nov 2025 10:43:11 +0100

To get the correct behavior, the 'Stands' node needs to be down furthest down the Map Layers list.
However, there are a lot of problems with the map currently, better solve them in a more stable .NET8 Heureka release since other libraries are used there.
