Re: Error messages

Do you have an intermediate flow that is used by multiple processes? Maybe that could be messing up a connection somewhere in the model, which is why it works fine when you connect everything manually. Or it could be trying to pull a process that outputs that flow but is messed up somehow.

Re: target invocation failed

Just a reminder that if you have installed for a single user then the .ini file will be under a different location than the wiki shows. On Windows 7 this is C:\Users\[user name]\AppData\Local\openLCA. AppData is a hidden folder. On Windows XP it is also in a hidden folder somewhere under your user f...

Re: Uncertain parameters

Joyce - as a workaround I think you can use parameters for the mean and other values within a distribution.

Re: Insert new process

If you created new processes there should be a reference output flow associated with them. I'm not sure why you want to use the output from one process as the output for a second, but you'll need to find those reference flows and add them. If you can provide more specific information, maybe with scr...

Contribution tree question

I'm not clear what the values and percents in the contribution tree represent. Are they the sum of all processes upstream, the direct impacts from a process, or something else? Part of what is confusing me is how the contribution of something in the 4th level of the tree can be larger than the eleme...

Pedigree uncertainty

A few questions about the use of pedigree uncertainty: 1) If the uncertainty type is kept as "No distribution", will the pedigree uncertainty be taken into account during a monte carlo simulation? 2) If a normal or lognormal distribution is selected will the pedigree uncertainty be used? 3) Once a p...

Re: small differences in LCIA with openLCA vs. ecoinvent web

I don't have access to ecoinvent, but is it possible that one of the two is using old GWP factors?

Re: Contribution of individual flows to each impact

Thanks Andreas. If I have feature ideas or requests is it best to post them on the sourceforge site?

Contribution of individual flows to each impact

When running an impact assessment calculation for a product system, is there any way to determine the contribution of individual emission flows to the impacts caused by a product? In the example below I'd like to know what emissions from "diesel, combusted in industrial equipment" are contributing t...
