Texture Mapping Space Shuttle Example Model Volume Rendering • Rendering volume elements based on their variable (adjust transparency based on a variable, like velocity). • User control of transfer function relating opacity and variable. • Native OpenFOAM format reader in EnSight 9.2 • Handles steady state, transient (variable, coordinate, changing connectivity). • Direct reading of parallel OpenFOAM files without the slow reconstructPar step. • No intermediate steps for user to run (foamToEnsight), nor extra filespace used. • Most all models (whether steady state or transient) appear like transient models in EnSight • Steady State – Multiple iteration solutions are automatically read into EnSight as “timesteps”. – Can easily just change “timestep” value to automatically see solution. – Use Calculator functions to average select iterations or to estimate convergence/iterational changes. • Transient – Each iteration is a separate timestep • Standard Reader – File>Open – Select your ‘controlDict’ file, Choose OpenFOAM reader – There are Advanced options to control specific naming/conventions • Quick Reader – ‘cd’ to the directory above the system directory – Type ‘ensight92 –Eensfoam’ – Uses all default options and directly reads the data files Log Analyzer • Detonation of depth charge in a fluid • 2D, Transient • Isosurface of alpha1 • Decent spatial and temporal resolution, but only 2D • Large Eddy Simulation • Compressible, LES, Multiphase • Similar to 2D model, but done in a confined box, at high resolution. • 3D, Transient • Parallel File Reader • Wall of water released to flow over example city geometry. • 3D, Transient • Texture map for water surface • Example 2D airfoil run. Grid reasonable fine for RANS solution • 2D, Transient • Cp profile graph updating with timestep. EnSightCFD EnSight CFD • Only CFD related analysis & visualization • A simplified GUI EnSightCFD • Desktop tool • Most of the capabilities you need most of the time • Entry level product • No training required EnSightCFD • Version 3.0/3.5 – Full Feature calculator – Structured part loader – All Right click and click-n-go from EnSight – Native Apple support – Multi-language support EnSightCFD -- FREE • Free version – Full Featured – Limited problem size – ALL CFD Readers – Watermark – No Royalty Parts • Fewer fonts • Fewer animation outputs Example Animation.
