Is it possible to return to OpenLca 1.8 after updating to I.9?. This new versión has memory allocation problems and doesn't display General Information properly when running a product System.

Yes, you can. The 1.8 versions are still on the openLCA server: http://www.openlca.org/wp-content/uploads/2019/02/

The databases should be compatible between both versions so that it should be possible to use the same database with openLCA 1.8 and 1.9.

Could you also provide more information about these errors so that we can fix them in future versions:

  • Which database do you use and how big is the product system (information from   the statistics page)? In which kind of calculation do the memory problems occur that were not present in v1.8: analysis, MC simulation?
  • Could you attach a screenshot of the `General information` that are not properly displayed?
  • Which operating system do you use?

Thanks!

Regarding the memory settings: I created an issue to track this: https://github.com/GreenDelta/olca-app/issues/96. It should be possible to change the maximum heap memory in the `eclipse.ini` file as described in the issue.

Regarding the error in the `General information` page: does this only occur in openLCA 1.9 but not in openLCA 1.8? Do you get the same error with every product system? Is there an error message in log-file (Help > Log file)? Thanks for helping to solve these issues!
