In Dialux 4.13, we have results for the post-curfew case (1.5%), but the result of ULR is 0% for the pre-curfew case (more luminaries added to the model than the post-curfew case). I have used the post-curfew case file to run the pre-curfew case again, but still get 0.0%. How to fix this? Thanks.

Pre-curfew

Post-curfew
