Altair receives IndustryWeek’s 1994 “Technology of the Year“ award for OptiStruct

“We appreciate and honor the advancements in optimization enabled by the late Dr. Harold Thomas, a true technology leader, friend, colleague, and inspiration to our global family. Harold had been part of Altair since the early 90’s when we hired him to develop OptiStruct.”

- James R. Scapa, Chairman & Chief Executive Officer

Sailing to Success

Altair supported the PACT95 challenger syndicate for the ’95 Americas’ Cup by optimizing their inner hull structure. The beautiful yacht named “Mermaid” was the fastest of the challenger series. Sailing legend Dennis Connor chose it over his own to go up against defender New Zealand in the America’s Cup.

Designing the vehicle of tomorrow

There is a race to create the first truly commercial autonomous vehicle. Altair’s software technology provides solutions to simulate control and electromagnetic systems for a safer and more efficient way of travelling.

To accelerate early-phase automotive design, Altair developed a unique 3-stage concept development process called C123. Each stage deploys optimization technology to provide designers with structural data relating to mass and performance attributes. C123 facilitates informed design decisions and target ‘trade-offs’.
