OpenLCA crashes during Monte Carlo Calculation

Question

Whenever I am trying to do a Monte Carlo Simulation (even just 1 iteration) OpenLCA crashes when pressing "start". I have already allocated more memory. The log file showes the following:

Has anybody else encountered this problem?

Answer 1

I had to use the ecoinvent 3.9.1 n2 version before as the new one wasn't available to me, but the problem is resolved now using the ecoinvent 3.9.1 n3_20230629 version

Answer 2

Hi, does the normal calculation work, can you please check? It is possible that you have an ill-specified system (technology matrix that is singular) e.g. when you have several rows / coloums entirely 0, due to a parameter setting.

Thank you,

Andreas

Hi Andreas, thank you for your response! The normal calculation does work. I also checked whether or not there is the same problem using a mac notebook, but on that one the Monte Carlo Simulation works. The notebook just doesn't have enough RAM to do the iterations somewhat quickly, so that will not fix my problem . Maybe it is a Windows problem?
