Open source ice flow model

WebShallow Ice Approximation (SIA) is a simple method to model ice flow without having to solve full-Stokes equations. [6] The approximation is best applied to ice sheet with a small depth-to-width ratio, without many sliding dynamics and a simple bed topography. [7] SIA does not include many forces on an ice sheet, and can be considered a 'zero ...

Web14 de jun. de 2024 · Abstract. Ice rises and rumples, sites of localised ice-shelf grounding, modify ice-shelf flow by generating lateral and basal shear stresses, upstream compression, and downstream tension. Studies of pinning points typically quantify this role indirectly, through related metrics such as a buttressing number.

Webmodel runs that are fairly close to the runs already performed in generating the training dataset. With the exception of Brinkerhoff and others (2024), this idea has never been exploited in ice flow modelling. Yet – from a CFD point of view – the most accurate and most expensive ice flow model, the Stokes model, WebThe flow model is MATLAB based and you will need a MATLAB installation to run it. Installing Úa is simple: Just download/clone the code from github. Put all the files into one folder and make sure that this folder is on the MATLAB path. You can then test if it runs by writing Ua [Ret] in the MATLAB command line, and you are done! Úa is installed!
