Abstract:
Hybrid Finite Element/Finite Volume (FE/FV) methods have been employed to study oceanic circulation in a simplified domain consisting of both non-moving and moving ice floes. Our hybrid FE/FV flow solver combines the merits of both finite element and finite volume methods, and is highly sophisticated, robust and is a first of its kind approach extended for studying ocean ice dynamics and dispersion. Sea ice dynamics is one of the key components of ocean circulation models. The ultimate goal through the present project is to develop a highly accurate ice dynamics model that can be used to predict ice-edge positions, velocities for offshore operations, short term forecast for waterways, and also for long term global climatic studies. Preliminary results show that hybrid FE/FV methods can be successfully extended for studying ocean ice dynamics, through coupled implementation of automatic mesh movement. Movement of an isolated ice floe through the ocean and also waves impacting multiple dynamic ice floes are successfully simulated while maintaining the mesh integrity.
