Quantification of Computational Uncertainty for Molecular and Continuum Methods in Thermo-Fluid Sciences.

This paper presents a review of computational uncertainties in scientific computing, as well as quantification of these uncertainties in the context of numerical simulations for thermo-fluid problems. The need for defining a measure of the numerical error that takes into account errors arising from different numerical building blocks of the simulation methods is discussed. In the above context, the effects of grid resolution, initial and boundary conditions, numerical discretization, and physical modeling constraints are presented. [ABSTRACT FROM AUTHOR]
