Simulations of moist convection by a variational multiscale stabilized finite element method
Marras, Simone; Moragues, Margarida; Vázquez, Mariano; Jorba Casellas, Oriol; Houzeaux, Guillaume (2013-11-01)
Article
Accés restringit per política de l'editorialA variational multiscale stabilized finite element scheme is presented for the solution of moist atmospheric flows. The fully compressible Euler equations are coupled to a system of three advection equations that model the ... -
Variational multiscale stabilization of finite and spectral elements for dry and moist atmospheric problems
Marras, Simone (Universitat Politècnica de Catalunya, 2012-12-10)
Tesi
Accés obertIn this thesis the finite and spectral element methods (FEM and SEM, respectively) applied to problems in atmospheric simulations are explored through the common thread of Variational Multiscale Stabilization (VMS). This ... -
Variational multiscale stabilization of high-order spectral elements for the advection-diffusion equation
Marras, Simone; Kelly, James F.; Giraldo, Frank X.; Vázquez, Mariano (2012)
Article
Accés restringit per política de l'editorialOne major issue in the accurate solution of advection-dominated problems by means of high-order methods is the ability of the solver to maintain monotonicity. This problem is critical for spectral elements, where Gibbs ...
