Frequent Crashing When Running Results

Question

Yet another instance of OpenLCA shutting down when running the calculations. Not sure if this is a bug for v 2.0.3, please advise.

Answer 1

Sorry, if you want to get support you need to explain more. When does this happen, what is your system, etc. Otherwise it leaves me thinking: yet another user that just wants to troll ;)

Also, in any case I would advise openLCA 2.0.4 as this is out. I know that for some LCA users this is a new thing, but as with a web browser, you would also not stick with an older version because you started your project with that. You can edit your question to post more details about when this crash happens, thank you.

ok, so you found it; openLCA uses a matrix to calculate results, this matrix must not have linearly dependent rows since it then cannot produce all result answers needed; two full rows of 0 are of course linearly dependent and thus violate this requirement. Mathematically speaking, the matrix is then singular and cannot be inversed. Good! And this is not a matter of the version of openLCA unless you go back to version 1.2 or so where we also had the sequential calculation.
