OK, I can't upload any files yet so I'll have to describe. Looking at OS report in Timetep, a line graph for operative temperature shows the expected fluctuations throughout the weather year from 2006-2007. Fine. It also shows a line running from the first point in 2006 to a point at the start of 2017, where it populates a much more sparse and messy graph where points connect horizontally backwards to other points, as if the sequence is not related to the plotted dates. It looks like someone's done a scribble on the end of the graph effectively.
I thought it might be the .ddy file being based on a separate year, and the sparser second graph was just showing the design days, but looking at the .ddy and .epw files in elements shows they're all for the same year, which is actually 2013, not 2006. The .epw and .ddy files are drawn from a 2006-2018 dataset, so it may just be ignoring the year stamp when it runs the simulation?
The weather files are from here: link text
Any ideas? I'm quite new to this and learning as I go. Cheers.
