What’s new in openLCA?

 We are happy to announce the release of our newest version: openLCA 1.9!

 

A vast list of newly developed and enhanced features will provide you with:

User-friendly operating components, for MacOS and Windows users alike (I) some upgrades, bug fixes and improvements (II) as well as an enhanced data quality and deeper understanding of your process flows (III).

I Enjoy an installation-free quick Start of openLCA, smooth data im- and exports as well as detachable tabs for an efficient workflow while overlooking your whole project. MacOS users now calculate their flows just as quickly with fast numerical libraries.

II Feel free to explore our realistic waste water treatment modelling methods and the fully supported updated collaboration server – our unique knowledge sharing product.

III Not convinced? Than have a look at our new Nested product systems, intertwining product system into product system and double check those with Process- specific Monte Carlo Simulation in case of uncertainties. The new ‘linking properties’ feature displays a comprehensive provider check of your product or waste flows pinpointing interlinkages. Linked in – and outputs can be traced by upgraded product system statistics. And there is more: enhanced Sankey Diagrams neatly visualises your energy and material flows.

Nested product systems

Link a product system as the provider for an input flow to a process of another product system. Just drag and drop a product system into the model graph of a different product system and connect it to one of the input flows via ‘search recipients for‘. The contributions of the sub product system to the overall results are displayed e.g. in the impact analysis and contribution tree results. Details about nested product systems are available on the openLCA GitHub page.

Process-specific Monte Carlo Simulation results

The uncertainty results of all processes and sub product systems that are part of a product system can now be displayed separately in the Monte Carlo Simulation tab. To easy navigation, individual processes can be pinned.

New 'linking properties' tab

The new ‘linking properties’ feature (accessible via the main menu entry Database -> Check linking properties) performs comprehensive provider checks and displays the results in a table:

 

  • Do processes without a default provider exist in the active database?
  • Do product or waste flows exist in the active database that have multiple providers?
  • Which product flows in the active database have multiple providers?
  • What provider linking options are uncritical when working with the active database?

Upgraded product system statistics

The uncertainty results of all processes and sub product systems that are part of a product system can now be displayed separately in the Monte Carlo Simulation tab. To easy navigation, individual processes can be pinned.

openLCA for MacOS *improvements*

openLCA has a more than solid base of MacOS users. The most recent release of openLCA holds some improvements particularly for this user group:

  • Embedded Java Runtime
  • Quicker libraries for calculating results
  • More lean and more recent eclipse platform
  • Improved build process of openLCA for MacOS. Actually, quite a large improvement which will probably remain unnoticed by most openLCA users sticking to just LCA modelling. However, more technically-oriented users may want to learn more by reading about this improvement on out openLCA GitHub page.
  • … and of course all other features of openLCA 1.9
Detachable tabs

Detach tabs and move them around on your screen as you like. Dragging and dropping a detached tab next to an existing tab in openLCA reverses the detaching. Detaching tabs allows you to run openLCA in a single-window and multi-window mode. This is particularly handy when working with several screens!

 

Updated reference data

openLCA 1.9 includes updated reference data that matches the most recent releases of data sets, databases and LCIA methods available on https://nexus.openLCA.org and https://data.openLCA.org.

Additional improvments and bug fixes

As always, the most recent openLCA release ships with several minor improvements and bug fixes:

  • Fix of changes in the parameter overview not being picked up as a change by the LCA Collaboration Server
  • Fix of a bug when using IPC server
  • Fix of error ‘Bundle ‘org.eclipse.fx.ui.workbench3′ cannot be resolved’
  • Fix of an error with precalculated LCI results

Download and support

How to get the latest version?

The most recent version of openLCA is always available at the openLCA Downloads website. You can use either the installer (your will need to de-install your older version) or the .exe file included in the zip file also provided in the downloads page (no need to de-install your older version). In both cases, when you open a database you will be asked to update it to the new database format. By clicking OK, you accept the conversion. The content of the database will not be affected, only the structure. Have in mind that this process cannot be reversed. Once your database has the new database structure it cannot be opened with earlier openLCA versions.
