Hi, I have a try of the wind model in SkyHelios for a simple "street canyon" file. The loading is OK I can see that my 2 buildings are loaded and I also see a rectangle being an extend of my geometry file (+25 m on x axis and +15 m on y axis). However when I use the "Calculate area" box, even though I tick on the "Area of interest (AOI)" line and I set the coordinate of the extend, the resulting file only has values within my street canyon. Is there a way to have wind speeds for all the extend in the resulting output file ? Thanks a lot. Jérémy PS : I did not find how to add screenshot. If you need some let me know (and let me know how does it work).
