Monte Carlo Simulation error - mu values required #1262

Closed BiancaWe22 closed 2 months ago

BiancaWe22 commented 3 months ago

Issue

Hi, I'm trying to perform a Monte Carlo Simulation but when I include the uncertainty of Technosphere this error message appears: "Real location (mu) values are required for lognormal uncertainties." Last week, I didn't have any issues with performing the MC simulation. Since that, I have only changed the uncertainty values using the pedrigree matrix, so I don't know if this is causing the problem..

I would be very thankful, if someone can help me and tell me what I need to do to provide the mu values and solve the error.

Thanks, Bianca

The error was solved by selecting "no uncertainty" for the flows which have a negative value and for those which have only unit as a unit.

Happy this was resolved, I'll close this for now.
