Default cut-off option

Hi, After accidentally hitting the new product system "ok" button without setting the cut-off criteria a few times I wonder if it is not possible to add a setting option for a "default value" that can be set by the user? A default of 0 is the worst possible choice if you have a big IO-DB. Killing th...

Re: Cost year in openLCA?

Oh, I just saw the description in the currency itself. It does say 2015 there. I don't know how I missed it. Sorry. It would still be good if it was specified somewhere in the documentation though. Furthermore information on which year the actual cost was collected would be highly valuable in order ...

Cost year in openLCA?

Hi, This might be the wrong section to post this question, so feel free to move it. I didn't know where to put it. I am trying to use the ecoinvent v3.3 database for an LCA and added value assessment and also couple the foreground system to the relevant sectors in SHDB. This is very difficult when t...

Using parameters in flow properties

Hi, I am using openLCA v1.5.0 and try to use multiple flow properties for custom created flows to make it possible to use different flow properties, such as dry substance, moisture content, mass and energy values of individual flows. Naturally these properties are not permanently fixed relative to e...

Re: Ecoinvent v3 exchange properties

Thanks for clarifying. Now that I know I should stop looking I can proceed and add the necessary flows to construct the mass balance myself. I think you are right. I have not seen these properties in other software either. They would however be useful sometimes, as in my case. I believe people inter...

Ecoinvent v3 exchange properties

Hi, I am trying to keep track of mass and energy balances in my model using ecoinvent v3.3. I can however not find the exchange properties anywhere within the database imported to openLCA. I am particularly keen on carbon contents, dry mass, water content, water in wet mass and wet mass associated w...

adding uncertinty to global parameters

Hello, I'm trying to get the hang of openlca v1.5 since it seems much more user friendly than simapro. I am however confused. In the list of global parameters in my process parameters tab there is an uncertainty field for the global parameters, but I can not find anywhere where the uncertainty data ...
