On the evolution equations of interfacial variables in two-phase flows
Giuseppe Orlando, Paolo Francesco Barbante, Luca Bonaventura
Many physical situations are characterized by interfaces with a non trivial shape so that relevant geometric features, such as interfacial area, curvature or unit normal vector, ca…
A seamless, extended DG approach for advection-diffusion problems on unbounded domains
Federico Vismara, Tommaso Benacchio, Luca Bonaventura
We propose and analyze a seamless extended Discontinuous Galerkin (DG) discretization of advection-diffusion equations on semi-infinite domains. The semi-infinite half line is spli…
Resiliency in Numerical Algorithm Design for Extreme Scale Simulations
Emmanuel Agullo, Mirco Altenbernd, Hartwig Anzt +33
This work is based on the seminar titled ``Resiliency in Numerical Algorithm Design for Extreme Scale Simulations'' held March 1-6, 2020 at Schloss Dagstuhl, that was attended by a…
Flexible and efficient discretizations of multilayer models with variable density
Luca Bonaventura, José Garres-Díaz
We show that the semi-implicit time discretization approaches previously introduced for multilayer shallow water models for the barotropic case can be also applied to the variable…
The TR-BDF2 method for second order problems in structural mechanics
L. Bonaventura, M. Gomez Marmol
The application of the TR-BDF2 method to second order problems typical of structural mechanics and seismic engineering is discussed. A reformulation of this method is presented, th…
A novel dowscaling procedure for compositional data in the Aitchison geometry with application to soil texture data
Federico Gatti, Alessandra Menafoglio, Niccolò Togni +4
In this work, we present a novel downscaling procedure for compositional quantities based on the Aitchison geometry. The method is able to naturally consider compositional constrai…
