Easy and Versatile Analysis of PowerFLOW Results

Visualization of Peterbilt truck using Exa PowerVIZPowerVIZ´ is Exa’s high-performance 3D visualization solution for PowerFLOW® measurements and PowerACOUSTICS® spectral analysis results. Fast visualization of large transient data sets, the ability to easily combine several powerful visualization techniques, and options to interactively examine results in 3D or automatically generate complete analyses with PowerINSIGHT allow you  to extract maximum value from your simulation data as never before.


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 an 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 photorealistic 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.




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 the 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 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



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





Fluid Measurement Visualization

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.


Photorealistic Rendering

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


Stereo Viewing

View PowerVIZ data in 3-D stereo; with the proper graphics hardware and glasses, your PowerFLOW® simulation data was never easier to communicate


Comparative Analysis

Apply the 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.
