Setting the Scene for Accurate Visual CFD Comparisons Using Ray Tracing Author Klapwijk, M.D. (TU Delft Ship Hydromechanics and Structures; Maritime Research Institute Netherlands (MARIN)) Lemaire, Sébastien (Maritime Research Institute Netherlands (MARIN); University of Southampton) Date 2021 Abstract Increased graphical capabilities of contemporary computer hardware make ray tracing possible for a much wider range of applications. In science, and numerical fluid mechanics in particular, visual inspections still play a key role in both understanding flows, predicted by computational fluid dynamics, exhibiting features observable in real-life, such as interfaces or smoke, and when comparing such flows against experimental observations. Usually, little attention is paid to the visualisation itself, unless when the render is used solely for its eye-catching appearance. In this work, we argue that the use of ray tracing software can help make comparisons between computational and experimental fluid dynamics more robust and meaningful, and that, in some cases, it is even a necessity. Several visualisation problems which can be overcome through application of this methodology are discussed, and the use of ray tracing is exemplified for several common test cases in the maritime field. Using these examples the benefits of ray tracing are shown, and it is concluded that ray tracing can improve the reliability of scientific visual comparisons Subject computational fluid dynamicsray tracingBlendercomparison errorsmaritime engineering To reference this document use: http://resolver.tudelft.nl/uuid:73b5e576-b0a9-44ea-869f-fe022429e063 DOI https://doi.org/10.3390/jmse9101066 ISSN 2077-1312 Source Journal of Marine Science and Engineering, 9 (10) Part of collection Institutional Repository Document type journal article Rights © 2021 M.D. Klapwijk, Sébastien Lemaire Files PDF jmse_09_01066.pdf 30.25 MB Close viewer /islandora/object/uuid:73b5e576-b0a9-44ea-869f-fe022429e063/datastream/OBJ/view
