Influence of computational parameters on the evaluation of wind effects on the building envelope

This paper systematically examines the influence of the computational parameters on the computed wind loads on the building envelope. Parameters considered include : size of the computational domain, number of computational grid nodes, criteria used for the convergence of an iterating process and computing time requirements for different computer systems. In all four cases, computed results and computational cost (CPU time) are analyzed and for some cases comparisons are also made with the experimental data. By using this analysis a diagnostic system to monitor the computed results can be developed.Peer reviewed: YesNRC publication: Ye
