The Stochastic TR-BDF2 Scheme of Order 2
Tomás Caraballo, Macarena Gómez-Mármol, Ignacio Roldán
Our main objective in this paper is to develop a second-order stochastic numerical method which generalizes the well-known deterministic TR-BDF2 scheme. Since most stochastic techn…
Multi-rate Runge-Kutta methods: stability analysis and applications
Bernhard Bachmann, Luca Bonaventura, Francesco Casella +3
We present an approach for the efficient implementation of self-adjusting multi-rate Runge-Kutta methods and we introduce a novel stability analysis, that covers the multi-rate ext…
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…
Certified Reduced Basis VMS-Smagorinsky model for natural convection flow in a cavity with variable height
Francesco Ballarin, Tomás Chacón Rebollo, Enrique Delgado Ávila +2
In this work we present a Reduced Basis VMS-Smagorinsky Boussinesq model, applied to natural convection problems in a variable height cavity, in which the buoyancy forces are invol…
On a certified Smagorinsky reduced basis turbulence model
Tomás Chacón Rebollo, Enrique Delgado Ávila, Macarena Gómez Mármol +2
In this work we present a reduced basis Smagorinsky turbulence model for steady flows. We approximate the non-linear eddy diffusion term using the Empirical Interpolation Method, a…
