General / Python in Umberto
« Last post by anfi96 on July 06, 2020, 16:13 »
Hallo, ich benötige dringend Hilfe!

Ich habe ein Problem. Ich versuche anstelle mit einer User defined function Berechnungen mit Python in Umberto durchzuführen. Dafür möchte ich Variablen verwenden, die ich auch in den Transitionen des Modells verwende. In Python kann er aber anscheinend nicht auf die Variablen aus dem Modell zurückgreifen und es kommt die Fehlermeldung dass sie nicht definiert sind.
Was muss ich tun, damit er auf die Variablen zurückgreifen kann?

im Anhang die Abbildung eines ganz simplen Beispiels und die Fehlermeldung.

Schonmal vielen Dank für Eure Hilfe!

General / Model into a transition?
« Last post by maphraw on June 13, 2020, 13:03 »
Hi there , I’m Jame.

in Umberto 5.6 it was possible to export a whole subnet or a whole calculated net into a spreadsheet, which you could import into a single transition and use this transition as a new one through export this transition.

I couldn't find a similar function in Umberto NXT LCA yet. Is there any possibility to create such a transition from exporting a spread sheet of a calculated net?

Thank in advance.
What is the difference between Umberto and others LCA softwares?
Thanks in advance. เกมสล็อต

I am also very new to Umberto and was wondering if it is possible to Import EcoSpold Data to Umberto. The last post I have seen on this topic is from 2015. Surely there is a way to use free Datasets, not only by formatting it to an Excel sheet. Otherwise I would be almost completely bound to data I have to buy and this shouldn't be the state of the art. Don’t you agree?

Dear hearthot2543,
You can import linear specifications with a right click on a process, but you need to use the correct template. You can get this if you export the input/output data (linear specification) from a successfully calculated model.

An alternative way is to specify a carbon footprint or other LCIA impact factor for a custom material. Our manual in chapter 6.5 will help you how to set this up.

I´m very new in Umberto and I´m working on the trial version of NXT LCA (sorry to have put the post in the wrong board!) at the moment. So please excuse my potentially simple question:
How do I import datasets (simple linear input/output process specifications) from free database like ProBas? Which toolbar do I have to use? Supposed I don't have the econinvent database yet.
Thank you
