Reducing Spatial Discretization Error with Linear Discontinuous Source Tilting in Iterative Quasi-Monte Carlo for Neutron Transport

Samuel Pasmann, Ilham Variansyah, C. T. Kelley +1

Recently, iterative Quasi-Monte Carlo (iQMC) was introduced as a new method of neutron transport which combines deterministic iterative methods and quasi-Monte Carlo simulation for…

iQMC: Iterative Quasi-Monte Carlo for k-Eigenvalue Neutron Transport Simulations

Samuel Pasmann, Ilham Variansyah, C. T. Kelley +1

The Iterative Quasi-Monte Carlo method, or iQMC, replaces standard quadrature techniques used in deterministic linear solvers with Quasi-Monte Carlo simulation for more accurate an…

A Quasi-Monte Carlo Method with Krylov Linear Solvers for Multigroup Neutron Transport Simulations

Sam Pasmann, Ilham Variansyah, C. T. Kelley +1

In this work we investigate replacing standard quadrature techniques used in deterministic linear solvers with a fixed-seed Quasi-Monte Carlo calculation to obtain more accurate an…

Convolutional Autoencoders for Reduced-Order Modeling

Sreeram Venkat, Ralph C. Smith, Carl T. Kelley

In the construction of reduced-order models for dynamical systems, linear projection methods, such as proper orthogonal decompositions, are commonly employed. However, for many dyn…

Parallel implementation of electronic structure eigensolver using a partitioned folded spectrum method

E. L. Briggs, C. T. Kelley, J. Bernholc

A parallel implementation of an eigensolver designed for electronic structure calculations is presented. The method is applicable to computational tasks that solve a sequence of ei…

Condition Estimates for Pseudo-Arclength Continuation

K. I. Dickson, C. T. Kelley, I. C. F. Ipsen +1

We bound the condition number of the Jacobian in pseudo arclength continuation problems, and we quantify the effect of this condition number on the linear system solution in a Newt…
