Dynamic control of the WIND CFD code

Obtaining robust solutions from computational fluid dynamics (CFD) computations remains a topic of interest to the aerospace community. Typically, multiple analysis runs that require manual monitoring and intervention must be done to obtain acceptable solutions. This paper presents the results of efforts to evaluate a particular knowledge-based approach, called the runtime-manager (RTM), to reduce the need to manually monitor and intervene in running CFD codes, and to reduce the computational time needed to reach acceptable solutions. We also characterize the performance of the RTM in a way that allows CFD engineers to predict the potential benefits of using the RTM. Preliminary results suggests that the RTM can help reduce the number of labor hours to complete moderately complex analyses up to 75%, and help reduce computational time up to 44%. We describe the canonical tests and the relatively simple modifications made to the WIND code to achieve these results.
