Easy and Versatile 3D Visualization Analysis of PowerFLOW Simulation Results

PowerVIZ 3D Visualization Analysis

PowerVIZ® is Exa's high-performance 3D visualization solution for PowerFLOW® measurements and PowerACOUSTICS® spectral analysis results. Perform fast 3D visualizations of large transient data sets with the ability to easily combine several powerful visualization techniques and options to interactively examine results in 3D or automatically generate complete analyses with PowerINSIGHT® allowing you to extract maximum value from your simulation data.

PowerFLOW's unique ability to perform transient simulations on highly detailed geometry produces a wealth of highly detailed transient measurements. Powerful and sophisticated analysis techniques are required to analyze the results, understand the nature of the fluid flow, identify the impact on vehicle performance and thus gain the most value from the simulation. PowerVIZ provides a wide array of such techniques, including volume visualization, stereo viewer support, particle tracking, animations, quantitative analysis and the ability to export a visualization scene to photo-realistic rendering solutions like RTT's DeltaGen®. And of course, all of the standard visualization techniques expected in a modern fluids analysis tool are also available: fluid slices, isosurfaces and surface contours, fluid and surface plots and many others.

KEY BENEFITS

Super High-Performance

PowerVIZ is acknowledged by our customers as: easy-to-use with its interactive and intuitive user interface; high-performance on even the largest data sets; and very flexible with dozens of analysis techniques for nearly any need

Deep Product Performance Insight

PowerVIZ's best-in-class visualization techniques allow transient flow details to be identified, studied and communicated like never before

Realistic Communication of Results

Stereo viewing, real-time volume visualization, photo-realistic rendering and animations of transient effects enable clear and powerful communication of simulation results

Accurate Quantitative Analysis

Compute specific, meaningful quantities such as net force and mass flux or show detailed images to illustrate complex flow features. PowerVIZ has built-in features to compute specific, meaningful quantities such as force and torque acting on a body, mass flux or the ability to integrate any quantity in the fluid or on the surface

Soiling and Water Management

With the optional Soiling Module, particle motion, surface bounce and hit points are easily studied

Automation

PowerINSIGHT to standardize and automate production of PowerVIZ content, saving the analyst valuable time

CAPABILITIES & EXAMPLES

  • Can include streamlines, particle traces and hit points

Real-Time Volume Visualization and Animation

Volume visualization is a technique for directly displaying and manipulating a 3D scalar field in real-time; users may choose either direct volume rendering or volume-based isosurface rendering. PowerVIZ exploits the massive floating-point capabilities of modern graphics processors (GPUs) to perform real-time volume visualization — impractical on conventional CPU systems, as it is too compute-intensive.

PHOTO-realistic Rendering

Nearly all PowerVIZ visualization techniques can be exported as VRML and imported into photo-realistic rendering packages, such as DeltaGen, providing a life-like image of the vehicle with overlaid simulation results

Stereo Viewing

View PowerVIZ data in 3D stereo; with the proper graphics hardware and glasses, your PowerFLOW simulation data is easy to communicate

Comparative Analysis

Apply identical visualization technique to multiple measurement data sets simultaneously. PowerVIZ synchronizes the views as you manipulate the models in 3D to make comparison of results easy
