A Comparison of Data-Driven Reduced Order Models for the Simulation of Mesoscale Atmospheric Flow
Arash Hajisharifi, Michele Girfoglio, Annalisa Quaini +1
The simulation of atmospheric flows by means of traditional discretization methods remains computationally intensive, hindering the achievement of high forecasting accuracy in shor…
A scalar auxiliary variable unfitted FEM for the surface Cahn-Hilliard equation
Maxim Olshanskii, Yerbol Palzhanov, Annalisa Quaini
The paper studies a scalar auxiliary variable (SAV) method to solve the Cahn-Hilliard equation with degenerate mobility posed on a smooth closed surface Γ. The SAV formulation is c…
Filter stabilization for the mildly compressible Euler equations with application to atmosphere dynamics simulations
Nicola Clinco, Michele Girfoglio, Annalisa Quaini +1
We present a filter stabilization technique for the mildly compressible Euler equations that relies on a linear or nonlinear indicator function to identify the regions of the domai…
GEA: a new finite volume-based open source code for the numerical simulation of atmospheric and ocean flows
Michele Girfoglio, Annalisa Quaini, Gianluigi Rozza
We introduce GEA (Geophysical and Environmental Applications), a new open-source atmosphere and ocean modeling framework within the finite volume C++ library OpenFOAM. Here, we pre…
Validation of an OpenFOAM-based solver for the Euler equations with benchmarks for mesoscale atmospheric modeling
Michele Girfoglio, Annalisa Quaini, Gianluigi Rozza
Within OpenFOAM, we develop a pressure-based solver for the Euler equations written in conservative form using density, momentum, and total energy as variables. Under simplifying a…
