Numerical Accuracy

摘要

Many technical issues impact the accuracy of a mathematical model of a physical process or system of interest. This portion of the policy statement deals with only one issue: the numerical solution accuracy of the assumed mathematical model that is solved using numerical algorithms that are implemented in software and solved on a computer. Other issues, such as the assumptions of the mathematical model, appropriateness of the initial and boundary conditions, and the accuracy of the simulation results with respect to experimental data, are considered in the decision to accept or reject a manuscript for publication. However, these issues are not the topic of this policy statement. The intent of this policy statement is to improve the credibility and reproducibility of the numerical aspects of the simulation results.
