1. Simulation-ready 3D city models AMS Stimulus Final Presentation 2017-11-15

2. Hugo Ledoux Tom Commandeur Claus Nagel Stefan Trometer Svetlana Valger

3. Our 2 goals 3 1. automatic construction of the error-free

   3D city model 2. simulation of a pollutant in Amsterdam with CFD (advanced 3D methods)

4. 4 complex simulations == 3D triangulation of volume

5. Still a manual and painful operations in practice 5 70%+

   of her time

6. 1. modifications to our software to reconstruct 3D city models

7. 3dfier: automatic reconstruction of 3D city models 7

17. Modifications to 3dfier are open-source 18

18. 2. performing the simulation

19. Test area: Amsterdam Zuid 20

20. Some troubles with the simulation software 21 (a) (b) (c)

    (d) Figure 7: Problem zones of the original model (a,c); the regions obtained using SpaceClaim tool (b,d).

21. NOx distribution over time 22

22. New software: ANSYS Discovery 23

23. Scaling up: opens the door to more simulations 24 1.

    urban heat island 2. wind comfort for pedestrian at street level 3. wind loading on buildings 4. urban blast (from a bomb) 5. urban flooding simulations 6. noise simulation
