Iso-surfaces of Q criterion are ones that out-line flow
regions with local rotation, indicating a turbulent eddy.
“Q” is a mathematical quantity commonly used to illustrate
turbulent vortices in
a flow field.
To bring costs down, wind-energy firms are recognizing the design benefits of numerical simulation. Transitioning to a simulation-based design process lets OEMs optimize performance and increase a turbine’s power output.
A valuable tool in this process is Computational Fluid Dynamics (CFD) software. It has traditionally played a role in the design of rotorcraft, fixed-wing aircraft, and even wind-turbine blades. Previous limitations in computing power kept most simulations focused on small portions of a design with a limited inclusion of physical phenomena. Perhaps the most accepted use of CFD in the industry is for analysis of 2D airfoils. Although an important application, recent advances in computing power and software provide greater capabilities for wind-turbine designers.

Altair HyperView is a complete post-processing and visualization environment for finite element analysis, multi-body system simulation, digital video, and engineering data. HyperView combines advanced animation and XY plotting features with window synching to enhance results visualization. HyperView also saves 3D animation results in Altair’s compact H3D format, so users can visualize and share CAE results within a 3D web environment using Altair HyperView Player.
Amazingly fast 3D graphics and unparalleled functionality set a new standard for speed and integration of CAE results post-processing. Coupling these features with HyperView’s advanced process automation tools dramatically improves results visualization and reporting.

Program Manager – Durability
Product design in today’s environment requires careful attention to all aspects of the design, including such issues as sustainability, recyclability and durability of the product. Durability of ground vehicles can be particularly challenging because of the way the vehicle is used and the roads on which the vehicle is driven and the product design can change significantly during both the design phase and the product lifecycle. Testing the product is the most common way to verify durability, but testing is also expensive and time-consuming. Virtual durability testing methods in today’s computing environment offer rapid, repeatable predictions of the loads a vehicle will experience and the resulting life that the product will have when put into service.
