Space Shuttle Example Model

Texture Mapping

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.
