Yelmo is a 3D ice sheet ice shelf model designed specifically for simulating coupled ice sheet systems, solving the coupled dynamics and thermodynamics of ice sheet systems. Historical background : Yelmo was developed by the Yelmo team with the aim of providing a comprehensive 3D ice sheet ice shelf model to support coupled simulations of ice sheet system dynamics and thermodynamics. The development of this model responds to the demand for more accurate simulation of ice sheet ice shelf systems. Technical features : • Use high-order approximations to solve ice dynamics equations and improve simulation accuracy • Support multi physics coupling of ice heat hydrology to achieve more comprehensive system simulation • Simulate the process of ice shelf disintegration and analyze the stability of the ice shelf • Modeling the ice sea interaction process, including the melting of the bottom of the ice shelf • Analyze the stability of ice sheet edges and evaluate the mechanisms of instability • Modular design, easy to expand and customize Core functions : • Coupling simulation of ice sheet ice shelf system • Research on the process of ice shelf disintegration • Modeling of Ice Marine Interactions • Stability analysis of ice sheet edges • High order ice dynamics solution • Prediction of ice sheet evolution under different climate scenarios Application case : • Simulation and Prediction of Antarctic Ice Shelf Collapse Process • Stability analysis of the edge of the Greenland ice sheet • Research on the Impact of Ice Marine Interactions on Ice Sheet Dynamics • Prediction of ice sheet evolution under different climate scenarios • Analysis of the Relationship between Ice Shelf Stability and Sea Level Rise Limitations : • High demand for computing resources, requiring high-performance computing facilities • High requirements for the quality and accuracy of input data • The simulation of ice shelf collapse process still needs improvement • The coupling with climate models requires additional development • The learning curve is steep and requires familiarity with Fortran and ice dynamics Input parameters : • Geometric and physical parameters of ice sheet (thickness, rheological parameters, etc.) • Climate forcing data (temperature, precipitation, etc.) • Ocean forcing data (seawater temperature, salinity, etc.) • Boundary conditions and initial conditions • Simulate time steps and total duration Output result : • Ice sheet velocity field and thickness distribution • Evolution of temperature field • The process of ice shelf disintegration • Ice sea interaction parameters • Ice sheet edge stability refers to
