ICEM CFD Meshes for Drag Prediction Workshop Structured

ICEM CFD Meshes for Drag Prediction Workshop • Structured Multiblock Meshes for WB & WBNP configuration • Unstructured Tetra + Prism Meshes • Three unstructured meshes for each configuration based on size of the mesh • Prisms & Pyramids can be readily converted into tetras for solvers that can not handle prism & pyramid elements

Files • ICEM CFD files, Plot 3 D files and CGNS files are available • CGNS files are written by ICEM CFD CGNS translator using CGNS library version 2. 1 • Plot 3 D files are written with Double precision, Formatted, no IBLANK array with ‘Whole’ data layout. • Contact senthan@icemcfd. com for different format of the mesh • Wing-body configuration mesh files contains “wb” in the name, Wing-Body-Nacelle-Pylon configuration mesh files contains “wbnp”
