Application of physics-constrained data-driven reduced-order models to shape optimization
Autor: Hamid R. Karbasian, Brian C. Vermeire
Publikováno v: Journal of Fluid Mechanics. 934
This study proposes a novel approach for building surrogate models, in the form of reduced-order models(ROMs), for partial differential equation constrained optimization. A physics-constrained data-driven framework is developed to transform large-sca

Optimal Runge-Kutta Stability Polynomials for Multidimensional High-Order Methods
Autor: Siavash Hedayati Nasab, Carlos A. Pereira, Brian C. Vermeire
Publikováno v: Journal of Scientific Computing. 89
In this paper we generate optimized Runge-Kutta stability polynomials for multidimensional discontinuous Galerkin methods recovered using the flux reconstruction approach. Results from linear stability analysis demonstrate that these stability polyno

Paired explicit Runge-Kutta schemes for stiff systems of equations
Autor: Brian C. Vermeire
Publikováno v: Journal of Computational Physics. 393:465-483
In this paper we introduce a family of explicit Runge-Kutta methods, referred to as Paired Explicit Runge-Kutta (P-ERK) schemes, that are suitable for the solution of stiff systems of equations. The P-ERK approach allows Runge-Kutta schemes with a la
