Hello,
I am using openlca 1.7.0. I have downloaded openLCA LCIA methods v.1.5.7 from openLCA Nexus.
I imported the openLCA methods and these appear within Impact assessment methods folder. However, when I calculate any product systems, results are always a list of zeros for every item in the LCI.
I increased the maximal memory usage to 5000MB.

I copied examples from the log file.

Has anyone else had this problem?

Thanks
MarĂ­a

Hi Maria,
welcome -
as the log file says, a formula (or maybe more than one) is not following openLCA`s specification and therefore the calculation does not work.

ParentValue* machine_diesel_ratio failed: Unknown variable parentvalue

You should fix these formula issues and then recalculate. You can find all issues for formulas if you validate the database (right-click, then validate, on the database). Note that capital letters are not recognised in formulas.

Hth,
Andreas
