- •
A quasi-steady method is presented to simulate redistribution of snow on roofs.
- •
The boundaries of snowpack are updated in each phase.
- •
The angle of repose of snow is taken into account in the numerical simulation.
- •
A scaled test was conducted in a wind tunnel to validate the accuracy of the numerical simulation.
