The interplay between airflow and snow cover exhibits a complex coupling relationship. Over the course of hours or even days, airflow induces snow redistribution, while the redistributed snow, in turn, alters the airflow patterns. This research introduces a dynamic mesh technology that enables real-time updates to depict the evolution of the snow surface during prolonged snow drifting. The study employs a solver called driftScalarDyFoam, based on OpenFOAM, which divides the snow drifting process into stages and utilizes a snow transport equation to predict the spatial distribution of snow. The snow surface evolves based on an erosion-deposition model. The proposed method has been successfully validated through various measured cases, including snow distribution on a flat roof and around a building.
