Using a new radar sweeping technique most of the Earth's surfaces was digitized in 3D in approximately 10 days. SRTM acquired enough data during its mission to obtain a near-global high-resolution database of the Earth's topography. This paper describe how this revolutionary data set can be used to simulate anywhere around the Earth low altitude wind conditions for various atmospheric conditions. More specifically, we will describe the various processing steps necessary to convert this high-resolution terrain model provided by the SRTM database into a Computational Fluid Dynamic (CFD) volumetric mesh that is compatible with an open source CFD solver called OpenFOAM running in parallel on large West-Grid supercomputers. This work is the result of a new virtual wind-tunnel under development at the University of Alberta. In the paper, we present wind flow over the MountSaint Helens in the United States for a simple wind flow boundary condition. © 2006 IEEE.enginfo:eu-repo/semantics/conferencePaperBoundary conditionsComputational fluid dynamicsData visualizationDatabase systemsDetectorsEngineering geologyFluid dynamicsFluid mechanicsMesh generationNASARadarSupercomputersTheorem provingTopographyTracking radarVisualization3D data processingAlberta (CO)Atmospheric conditionsCFD solversData setsDigital terrain model (DTM)High resolutionsInternational symposiumLow altitudesOpen sourcesPay loadRunning inShuttle (CO)Shuttle Radar Topography Mission (SRTM)Terrain modellingUnited StatesVolumetric meshWind conditionsWind flowsWind simulationWind tunnelData processing2021-04-16Garcia, M.J.Boulanger, P.10.1109/3DPVT.2006.92
