Abstract

The roof of a well known shopping place in Amsterdam collapsed during a storm with heavy rain showers in 2002. One of the main problems was the malfunction of the draining system. Another problem was that driving rain water apparently washed over edges that where designed to hold the water. This short paper presents the progress of using Comsol to simulate the height of the water near the edges of an inclined roof during heavy rainfall and wind gusts. It is concluded that the combined application modes of Incompressible Navier-Stokes (ns) and Moving Mesh (ale) seems promising in simulating the height of the water near the edges of an inclined roof during heavy rainfall and wind gusts. However there are still a lot of features to be implemented before more realistic simulation results can be obtained.
