Performance Evaluation of Mixed-Precision Runge-Kutta Methods

Ben Burnett, Sigal Gottlieb, Zachary J. Grant +1

Additive Runge-Kutta methods designed for preserving highly accurate solutions in mixed-precision computation were proposed and analyzed in [8]. These specially designed methods us…

High order strong stability preserving multi-derivative implicit and IMEX Runge--Kutta methods with asymptotic preserving properties

Sigal Gottlieb, Zachary J. Grant, Jingwei Hu +1

In this work we present a class of high order unconditionally strong stability preserving (SSP) implicit multi-derivative Runge--Kutta schemes, and SSP implicit-explicit (IMEX) mul…

An EIM-degradation free reduced basis method via over collocation and residual hyper reduction-based error estimation

Yanlai Chen, Sigal Gottlieb, Lijie Ji +1

The need for multiple interactive, real-time simulations using different parameter values has driven the design of fast numerical algorithms with certifiable accuracies. The reduce…

A general linear method approach to the design and optimization of efficient, accurate, and easily implemented time-stepping methods in CFD

Victor DeCaria, Sigal Gottlieb, Zachary J. Grant +1

In simulations of fluid motion time accuracy has proven to be elusive. We seek highly accurate methods with strong enough stability properties to deal with the richness of scales o…

Two-derivative error inhibiting schemes with post-processing

Adi Ditkowski, Sigal Gottlieb, Zachary J. Grant

High order methods are often desired for the evolution of ordinary differential equations, in particular those arising from the semi-discretization of partial differential equation…

IMEX error inhibiting schemes with post-processing

Adi Ditkowski, Sigal Gottlieb, Zachary J. Grant

High order implicit-explicit (IMEX) methods are often desired when evolving the solution of an ordinary differential equation that has a stiff part that is linear and a non-stiff p…
