In this paper, this algorithm is described, and is evaluated with a test problem. Cone‐shaped distributions of various chemical species undergoing chemical reactions are rotated to simulate the transport and chemistry processes that occur in the atmosphere. The results obtained by using DSAGA‐PPM are more accurate than those obtained from a static grid with the same number of nodes. The computational cost associated with a static grid solution with the same level of accuracy is prohibitive. Because of its efficient use of computational resources, DSAGA‐PPM has the potential to improve the accuracy, or efficiency, or a combination of both in air quality models.}, number={D20}, journal={JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES}, author={Srivastava, RK and McRae, DS and Odman, MT}, year={2001}, month={Oct}, pages={24245–24257} }

This algorithm uses a higher order numerical scheme—the piecewise parabolic method (PPM)—for computing advective solution fields; a weight function capable of promoting grid node clustering by moving grid nodes; and a conservative interpolation equation using PPM for redistributing the solution field after movement of grid nodes. Applications of the algorithm to a model problem, in which emissions from a point source disperse through the atmosphere in time, reflect that the algorithm is able to capture not only the regional ozone plume distribution, but also the small-scale plume structure near the source. In contrast, the small-scale plume structure was not captured in the corresponding static grid solution. Performance achieved in model problem simulations indicates that the algorithm has the potential to provide accurate air quality modeling solutions at costs that may be significantly less than those incurred in obtaining equivalent static grid solutions.}, number={28}, journal={ATMOSPHERIC ENVIRONMENT}, author={Srivastava, RK and McRae, DS and Odman, MT}, year={2001}, month={Oct}, pages={4801–4818} }

A brief justification for adaptation is offered and adaptation criteria are stated. The NCSU adaptation algorithms DSAGA and SIERRA are described and results obtained with these algorithms are used to illustrate the adaptation issues. Grid quality, truncation errors added and reduced by adaptation, and current research areas are discussed. Qualitative analysis of grids produced by the adaptive algorithms reveals that conventional standards of grid quality are violated frequently in regions where solution improvement due to adaptation is evident. Alignment of the grid with solution features is shown to be a more appropriate indication of mesh improvement than cell shape. Benefits and weaknesses of r-refinement adaptation are summarized and areas for further research are noted.}, number={4}, journal={COMPUTER METHODS IN APPLIED MECHANICS AND ENGINEERING}, author={McRae, DS}, year={2000}, pages={1161–1182} }
