I'm doing a LCA for some process i created. i have no problem running the process in various impact assessments with consistant results. But when i try to run a Monte carlo sorting, i have strange results : The sorting runs normally on the inventory but when it comes to impact assessments, only some categories get non-zero values, the other being systematically 0.
To spice up this weird results, the categories that are systematically zero can change from one process to an other.
I don't know why i get this error because i set up the uncertainty on every flow. If you have any clue of what is happening, i will gladly discuss it with you !
Thank you !
