Abstract

Visualization of marginal ice zone dynamics M. Serrer,* S.B. Savage/ M. Saved* "National Research Council, Ottawa, Ontario, ^Department of Civil Engineering and Applied Mechanics, McGill University, Montreal, Quebec, ABSTRACT Ice floe dynamics in marginal ice zones are simulated using a discrete element model. The ice floes are modelled as random sized, inelastic circular discs floating on the water surface. Contact conditions are represented by a constant restitution and friction coefficients. The ice floes are driven by a uniform wind field. The simulations predict ice floe displacements, rotations, compaction and pressures. This paper focuses on animation and visualization of the simulation output. INTRODUCTION Marginal Ice Zones (MIZ) are broken ice fields which often form at the edge of the polar ice pack, next to open ocean. They form as a result of several processes that take place at the pack ice edge including the incidence of waves and increase of temperatures. A
