Seminar 34 -- Computational Wind Engineering: Good, Bad and Ugly

This product is a .zip file that contains files that consist of PowerPoint slides synchronized with the audio recording of the speaker, PDF files of the slides, and audio only (.mp3 format) as noted.

Computational wind engineering (CWE) is a specialized sub-set of the engineering application of computational fluid dynamics. The increasing availability of commercial CFD codes, combined with increasing computing power, is both a blessing and a curse to this application. It is a blessing in allowing for CWE to develop into a strong field within wind engineering, and a curse in that it has led and will continue to lead to the use of CFD for CWE without the required basic knowledge. "The judicial presumption of innocence does not hold in CFD. CFD results are wrong, until proven otherwise." Blocken, 2014.
