The Galerkin Numerical Modeling Environment (GNuMe), Part I: Overview
Naval Postgraduate School
TCS Building 240
In this talk, Frank Giraldo will describe the GNuMe framework that he has been using to develop and test geophysical fluid dynamics models. GNuMe is, in essence, a modeling environment that contains local element-based numerical discretization methods (spectral elements and discontinuous Galerkin methods), as well as a suite of time-integrators (explicit, fully-implicit, and implicit-explicit methods).
GNuMe contains the Non-hydrostatic Unified Model of the Atmosphere (NUMA) which is being used inside of the U.S. Navy's NEPTUNE weather system. NUMA is a 3D compressible Navier-Stokes solver specifically designed for atmospheric flows on both Cartesian and spherical domains. GNuMe also contains a non-hydrostatic ocean modeling component (NUMO), as well as a shallow water model with wetting and drying.
The goal of this presentation is to give the GENERAL AUDIENCE a feel for what GNuMe can and cannot be used for in order inform a potential user/collaborator of its capabilities and limitations.
