Version 2.5.0
2016-03-28
Upcoming: Planned for release next week!
Version 2.5 will be released next week. Here you can read about what's new.
Summary
- This release note also covers changes released in updates 2.4.0.1-2.4.0.9
- Version 2.5 contains serveral improvements and bug fixes
- For PlanWise, the support for CPLEX optimization solver has been changed, see instructions in the Readme.txt file here: http://heureka2-1.slu.se/Filerepository/SolverLinks/Cplex/
- The publication of 32-bit versions has ended
New features
Extended help documentation
As you may know, the Heureka Wiki is used as a complement to the actual help document to give more in-depth documentation, for example about models, and to serve as a reference dictionary to certain terms and concepts.
- The English help documentation is now fully translated
- New pages have been added to give a concentrated overview of Result Variables. There are help links in the applications to make it easier to find help on a certain variable.
- The documentation on Control Table settings has also been extended. You can right-click a control table parameter in for example PlanWise, and select "Show wiki page for parameter" to get more information.
- Documentation of Dead Wood handling has been added.
- A dictionary has also been added, which for example includes an explanation on how net present value is calculated.
- The help documentation chapter on nature conservation has been updated.
New web adress for download files
We have until know used an ftp-server for certain downloadable files, such as report templates, and input data templates. These have been move to http://heureka2-1.slu.se/Filerepository/.
Default regeneration species not only pine or spruce in PlanWise
When selecting regeneration species in the Regeneration Settings form in PlanWise, you have had the options to either select the site index species as converted to in Heureka (i.e. pine or spruce), or enter a specific species. This means that you have had to create a specific forest domain and a specific control category for each species group that you wanted to regenerate. As a new option, which is default, Species to Plant = Auto is now available. This function is very similar to selecting "Regeneration Species" as species to retain in cleanings and thinnings. Choosing Automeans that the new generation will be regenerated with the same species as was considered the main species in the preceding rotation. The regeneration species for the first rotation is determined automatically,see Main Species.
New result variables
- Stem Wood Density in result group Biomass.
- Management System in result group Treatment: Simplifies keeping track of which kind of management system that has been applied (Even-aged, Uneven-aged, or Unmanaged).
- SetAsideType in result groups TreatmentUnit and StandObjectData: Allows tou to specify if a treatment unit is a retention patch or edge zone whose management depends on a certain main stand.
Other changes
Marklund's biomass functions now default in new projects
Marklund's biomass functions are now the default biomass function when you create a new project. Marklund's function have been found to give more logical results since they include tree height. Information on what functions have been implemented can be found here: Biomass functions
Help function for installing SQL Server Express has been removed
Heureka's applications have had a built-in help function to simplify the installation of SQL Server Express. However, this function has worked poorly due to some unresolved access right, so the help function has been dropped. Instructions on how to install SQL Server Express manually is still available in the help documentation.
CPLEX solver support modified
Due to a somewhat unclear rights for distributing certain files owned by IBM CPLEX, the buult-in for CPLEX has been removed and replaced with a plugin. If you used CPLEX, there a a couple files you must place in a certain directory to make it work, instructions can be found here: http://heureka2-1.slu.se/Filerepository/SolverLinks/Cplex/
Alternative Summary Results available in TPG table view
This results group can now also be selected in the TPG-result view (PlanWise). Also, result variable Managment System has been added, which tells what Management System is used in the first rotation. If the Management System is changed in the second rotation, you can find that information in result variable Treatment.Management System.
More result variables always included in a simulation
This results group can now also be selected in the TPG-result view (PlanWise). Also, result variable Managment System has been added, which tells what Management System is used in the first rotation. If the Management System is changed in the second rotation, you can find that information in result variable Treatment.Management System.
Only 64-bit versions
From version 2.5 Heureka will be available only as 64-bit applications. StandWise' previous dependency to the old DirectX library verison 9 (for the 3D-functionality) has been removed and replaced with SlimDX open source library. This means that you can now run StandWise as a pure 64-bit application, and also run it on Windows 10 without having to install any version of DirectX, all files required are installed when installing Heureka.
Bug fixes
Bug fix: Third rotation not correct
In the treatment program generator (TPG), Heureka is often simulating three rotations. The third rotation has been too simplified, with a faulty timing of thinnings. Since the discounted value of that rotation is typically very small, the error should not have affected solution to any considerable extent, but the reported soil expectation values have not been correct. Read more about how soil expectation is calculated here: Heureka Dictionary: Soil expection value
Bug fix: Biomass in cut trees in precommercial thinning was not calculated
Result variables "Biomass in Cut Trees" in result group Treatment represent the amunt of biomass in cut trees, whether extacted from the forest or left as residues. For cleaning, this step was skipped but has no been fixed.
Bug fix: Biomass and carbon contents were not updated in the first five-year period after fertilization
This bug first occured in version 2.4 after changes were implemented in the handling of the biomass functions. The problem was that five years after a fertilization, biomass, and as a cosnequence carbon contents, were not updated compared to no fertilzation. Ten years after fertilization they were updated correctly. The bug has been fixed so that the carbon and biomass results five years after fertilzation are updated as expected.
Bug fix: Log Tally list in StandWise form index error
An indexing error has been fixed that affected the Log Tally list (available in StandWise only).
Bug fix/improvement: Can now choose installation folder when installing as MSI
When installing Heureka from an MSI-package, you can now changed the installation folder. We want to remind you that the MSI is nowadays what we recommend as first choice for installing, before ClickOnce.
Minor changes
- Result variable Rate is renamed to Discount Rate.
- Updated Plugin-versions
- Updated some button caption, so they now have consitent naming.
- When selecting result variables you will notice that their location in tree views has been rearranged in some cases, for example for Biomass Data.
- The naming suffix for variables that include all species have been changed to All Species, when needed to avoid confusion with values Per Species. The suffix has alternately been All Species, Total and empty.
