Hello Tobias,
thank you very much for your help, already two weeks ago.
I think what is rather confusing is the error message, maybe you could add something like "... Make sure all processes are properly defined in the main net."
Best regards,
Christian

Dear Christian, dear community,

we already solved this problem via email, but for our community I wanted to explain the problem and the solution.

After a not complete calculation negative stocks for electricity was caused. This happend, because on the main net level not all processes could calculate completly. The main challange here was to model a model which calculate without erros. When every process with electricity in the input side is calculated, the electricity dataset can deliver the energy.

Regards,
Tobias

Hello,

I am stuck with a problem in my current modell which I remember to have had before but forgotten how it was resolved. In a production process modell several processes use a created material electricity and a sub-net delivers the exactly same electricity material but the connection will stay with negative stocks at end of calculation (causing an error). In my current specific model another connection stays with a wastewater material instead of pushing it forward to the WWTP process...
Any help would be very appreciated. Still I did not try to delete the material and create it anew because of quite a lot of uses and because I would like to see if you know the problem.
Here a temporary copy of the model:

Dear Luca,

the results of the LCIA endpoint methods are the sum of different midpoint results. Each midpoint is calculated with a weighting factor to a point impact. If you want to determine specific categories, you should use a midpoint impact category.

For further information, have a look into https://sites.google.com/site/lciarecipe/project-definition

Kind regards,

General / Translate Points to Impact Measurments
« Last post by Luca on January 23, 2019, 14:21 »
Hi everyone,

for a project I used the LCIA "Damage to ecosystem, ReCiPe Endpoint (E,A) w/o LT". Now I know that my impact is 0.02points. How can I translate this to something more tangible?

If I am not wrong you determine the impact of damage to ecosystem with species lost per m². Could someone clarify this and tell me what I have to do?

Thank you very much.

Kind regards,

Luca

Hallo Rafaela,

wenn ich deine Frage richtig verstehe, dann kann man das wie folgt lösen:

im Input ist das Produktmaterial als Massenangabe, im Output ist das Produktmaterial als Massenangabe und als Unitangabe.

Je nachdem welche Fragestellung man nun beantworten will kann man
1) das Produkt mit der Einheit Unit als manuellen Fluss festlegen -> dadurch erhält man die Information wie viel Produkt als Masse produziert wird.
2) das Produkt mit der Massenangabe als manuellen Fluss festlegen -> dadurch erhält man die Information wie viele Produkte hergestellt werden.

Zur Umgehung der Allokation kann der manuelle Fluss auf 'neutral' gestellt werden. Wenn Punkt 2) berechnet werden soll, dann müssen im Input und Output die Massenmaterialien 2 unterschiedliche Materialien sein, ansonsten gibt es eine Fehlermeldung dass das Material unterschiedliche material types aufweist.

Ich hoffe deine Frage kann so beantwortet werden!

Grüße
Tobias

Hallo zusammen,
Kann man in Umberto LCA+ dem Produkt eine Massenangabe zuordnen, sodass das Programm automatisch die Massenangabe in eine Produktanzahl umrechnen kann?

Vielen Dank im Voraus,
Rafaela
