Numerical model of glacier thermo-mechanics
Entry ID: CNDA-ESP_SERF_REN2002-03199
[ Update this Record ]


Summary
Abstract: In English:
Three-dimensional transient model of glacier thermo-mechanics.
It consists of three main sub-models:
-Dynamical sub-model (full Stokes system).
-Thermal sub-model.
-Free-surface evolution sub-model.
The model is numerically solved by uncoupling the various sub-models by means
of an iterative procedure. The dynamical sub-model is solved by using a mixed
velocity-pressure Galerkin finite element method; the thermal model is solved
by using a streamline upwind (or modified artificial diffusion) Galerkin finite
element method; and the surface-evolution sub-model is solved by using
semilagrangian methods.

En EspaƱol:
Modelo tridimensional y dependiente del tiempo de termomecanica glaciar.
Costa de tres submodelos principales:
-Submodelo dinamico (sistema de Stokes completo).
-Submodelo termico.
-Submodelo de evolucion de la superficie libre.
El modelo se resuelve numericamente mediante un procedimiento iterativo que
desacopla los distintos submodelos. El submodelo dinamico se resuelve mediante
un metodo de Galerkin de elementos finitos con formulacion mixta
velocidad-presion; el submodelo termico se resuelve mediante un metodo de
Galerkin de tipo streamline-upwind (o difusion artificial modificado); y el
submodelo de evolucion de la superficie libre se resuelve mediante metodos
semilagrangianos.
