Description:
In this talk I will describe the GNuMe framework that we have 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.
