Analytic Accuracy Analysis for Unstructured Mesh Finite Volume Methods with Application to Aerodynamic Simulations
Abstract
The long-term objective of the research program of which this project was a part is to provide prescriptive guidance for generating meshes for fullaircraft configurations that will reduce solution error for a given number of degrees of freedom compared with meshes generated using today's bestpractices. To achieve this goal, we must be able to identify features in unstructured meshes that have an adverse effect on solution quality forcommonly used numerical methods for computational aerodynamics and we must develop techniques to modify meshes to reduce those effects.During the term of this sponsored project, we completed the first step: identifying mesh features that negatively impact the accuracy of commondiscretization schemes, including identifying which discretization approaches are particularly sensitive to variations in mesh properties.
