Yves-Marie Lefebvre, FieldView Product Chief at Intelligent Light, new Altair Partner Alliance (APA) member, gave June EATC attendees a sneak peek at their CFD post-processor. FieldView Express is now available for use by APA-enabled HyperWorks users.
FieldView and its APA counterpart, FieldView Express, are unique in that they are extremely powerful and efficient at reading data while also being easy to use and flexible enough to be run on any system from a laptop to the largest supercomputers. Yves-Marie discussed some of the current challenges in CFD and how there is an increased need for running more unsteady simulations. “In the past, running steady-state or time-averaged simulations was fine, it was accurate enough, and it was coming at a relatively low cost but for more accuracy, you have to go unsteady. Even if you have a flow that has steady conditions, if your flow is turbulent it is chaotic by nature, so for higher accuracy you need to go unsteady.” Unsteady simulations can be challenging and often require terabytes of data to generate a single run. This is where FieldView is key; it can post-process simulations in a matter of days that would otherwise take weeks or even months.
FieldView is used in research organizations like NASA, ESA and JAXA; aerospace companies including Boeing and Lockheed Martin; automotive giants like Toyota and their suppliers such as Valeo; as well as companies in energy, heavy industry and environmental industries worldwide.
Formula One racing is a highly-regulated sport where the car’s basic dimensions are dictated by the FIA technical regulations and the car’s shape is primarily driven by aerodynamic efficiency. Yves-Marie explains that these customers really push them; “Formula One is all about speed, speed, speed! Not just about speed on the track, it’s also the speed at which you develop… They have races every two weeks so they have to select the best designs, prove their ideas before they take them to the track because they only get one chance to bring the right part to the track and for them to show the benefit in terms of aerodynamic performance.”
Sufficient accuracy and fidelity in the CFD results are required to pick up on the correct trends from sequences of small design changes. This requires large unstructured meshes, efficient algorithms, and parallel efficiency for meshing, solving and post-processing. To process results quickly for Formula One, they must use faster software (FieldView), make better use of available hardware (8-64 cores, a lot of memory and a high-end graphic card), run more jobs concurrently and reduce the memory required for each job.
FieldView Express is now available to HyperWorks users via the Altair Partner Alliance. Use FieldView Express to:
- Quickly extract useful information from your simulations
- Compare results from multiple simulations, designs, conditions, even different solvers
- Deliver actionable data to engineers at the right time
- Utilize local & remote compute resources
- Automate workflows
- Speed development
