I'm new to openLCA and am trying to create water desalination product system for analysis however some of the elementary/product flows I require I need to add myself in order to evaluate them? I'm trying to add in a membrane which should be a product flow but am unsure how the system would evaluate it once I complete the setup as I'm only adding it as a product flow with no linkages? Would I need to source a link or input the general LCA results of utilising a membrane and how would I do this?
I am unsure how to set up a provider linkage as well if that is part of the solution?
I appreciate any feedback or help which can be provided
