Goal-oriented a posteriori estimation of numerical errors in the solution of multiphysics systems
Mahesh Narayanamurthi, Ulrich Römer, Adrian Sandu
This paper develops a general methodology for a posteriori error estimation in time-dependent multiphysics numerical simulations. The methodology builds upon the generalized-struct…
Efficient implementation of partitioned stiff exponential Runge-Kutta methods
Mahesh Narayanamurthi, Adrian Sandu
Multiphysics systems are driven by multiple processes acting simultaneously, and their simulation leads to partitioned systems of differential equations. This paper studies the sol…
Optimization of Vehicle Dynamics based on Multibody Models using Adjoint Sensitivity Analysis
Yitao Zhu, Corina Sandu, Daniel Dopico +1
Multibody dynamics simulations have become widely used tools for vehicle systems analysis and design. As this approach evolves, it becomes able to provide additional information fo…
A Sampling Filter for Non-Gaussian Data Assimilation
Ahmed Attia, Adrian Sandu
Data assimilation combines information from models, measurements, and priors to estimate the state of a dynamical system such as the atmosphere. The Ensemble Kalman filter (EnKF) i…
