Simulation-ready 3D city models AMS Stimulus Final Presentation 2017-11-15
Hugo Ledoux Tom Commandeur Claus Nagel Stefan Trometer Svetlana Valger
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 complex simulations == 3D triangulation of volume
Still a manual and painful operations in practice 5 70%+
of her time
1. modifications to our software to reconstruct 3D city models
3dfier: automatic reconstruction of 3D city models 7

Modifications to 3dfier are open-source 18
2. performing the simulation
Test area: Amsterdam Zuid 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).
NOx distribution over time 22
New software: ANSYS Discovery 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
thank you.
