The Schwarz alternating method for the seamless coupling of nonlinear reduced order models and full order models
Joshua Barnett, Irina Tezaur, Alejandro Mota
Projection-based model order reduction allows for the parsimonious representation of full order models (FOMs), typically obtained through the discretization of certain partial diff…
A Novel Partitioned Approach for Reduced Order Model -- Finite Element Model (ROM-FEM) and ROM-ROM Coupling
Amy de Castro, Paul Kuberry, Irina Tezaur +1
Partitioned methods allow one to build a simulation capability for coupled problems by reusing existing single-component codes. In so doing, partitioned methods can shorten code de…
Performance portable ice-sheet modeling with MALI
Jerry Watkins, Max Carlson, Kyle Shan +6
High resolution simulations of polar ice-sheets play a crucial role in the ongoing effort to develop more accurate and reliable Earth-system models for probabilistic sea-level proj…
Preconditioned Least-Squares Petrov-Galerkin Reduced Order Models
Payton Lindsay, Jeffrey Fike, Irina Tezaur +1
This paper introduces a methodology for improving the accuracy and efficiency of reduced order models (ROMs) constructed using the least-squares Petrov-Galerkin (LSPG) projection m…
