Model graph do not show processes

Question

I downloaded Open LCA 2.4 and Case Study "A Water Bottle". When opening der Process System the model graph does not show anything. Its the same when I manually create a new Product system graphycally. First of all the process shows up but when I want to integrate related processes nothing happens. Seems to be a display problem because calculating the results work well.

Answer 1

Try click right in the window and chose "parameter", then select "show flows", it should make your graph appearing. This was the solution I found in my case

The same problem was found by about a third of 30 student's laptop in my course in May 2025 using openLCA 2.4.1 - By accident I found the same workaround as Redge, but I do not know what causes it.

This may be a serious bug (at least my students were very frustrated until I found the workaround).
