工程仿真和有限元分析技术公司ANSYS已购买了OnScale，这是一项云工程模拟服务，该服务是在Thornton Tomasetti Weidlinger Innovation Accelerator中开发的。

TTWiiN is a technology incubator founded in 2015 after engineer Thornton Tomasetti merged with Weidlinger Associates, combining technology development in both firms into a division focused on commercializing those innovations. Terms of the deal were not disclosed by Ansys or TTWiiN. OnScale was developed from the Flex family of computer code developed in the 1980s, particularly PZFlex, which can solve large-wave propagation problems found in a range of fields.

“Originally, Flex was developed for seismic waves in the Earth’s crust,” says Ray Daddazio, senior consultant at Thornton Tomasetti, OnScale board member and the last CEO of Weidlinger before its merger with Thornton Tomasetti. “After the [first] Gulf War, the Department of Defense was looking to do better battlefield medicine—triage.”

Daddazio said one of the things that was done under the sponsorship of several defense agencies was add a piezoelectric finite element into the Flex wave propagation code, creating PZFlex. Ultrasonic research groups used PZFlex to solve large, complex problems.

“You could speed up the process of virtual simulations by 75%. It became the de facto standard in the medical ultrasound business for transducer design, and all of the major manufacturers used it. We began to get some real software licensing revenue, and it was a nice little business for us,” Daddazio says.

Cloud computing and the merger of Thornton Tomasetti and Weidlinger created a greater commercial opportunity. Even as Daddazio and Thornton Tomasetti Executive Chairman Tom Scarangello were beginning merger talks in Jacksonville, Fla., in 2014, both men realized that OnScale’s code was perfectly suited to become a cloud-native application and its calculations could be scaled to a place where engineering was moving. As a part of the merger agreement, Thornton Tomasetti agreed to invest $4 million in PZFlex.

伊恩·坎贝尔（Ian Campbell）于2017年担任重命名的OnScale首席执行官，并迅速利用其云潜力。

Scarangello说：“我们一直认为价值将在超声波行业及其周围，并继续挖掘出这种压电元素。”“伊恩（Ian）认识到它的云计算角度，因为世界正在朝着云计算旋转，并且拥有可以在云中有效，多物理问题的平台的价值。”

Scale为用户提供了对高性能计算群集的尽可能多的访问，因为他们需要解决复杂的工程问题。对于ANSYS，这意味着对其用户的更多解决问题。坎贝尔在一份声明中说，加入宾夕法尼亚州坎森堡的ANSYS“对我和我的团队来说非常令人兴奋”。

ANSYS产品高级产品副总裁Shane Emswiler在一份有关销售的声明中说：“客户需求各不相同，任何成功的云战略都必须使客户灵活地适应其独特的模拟挑战。”“为此，我们的云战略不仅满足了现有客户的需求，而且可以从模拟技术中受益的任何工程师，科学家或专业人士。”

回到TTWIIN，Daddazio和Scarangello拥有仍在开发的产品组合中，例如新的冲击和振动 - 隔离安装座技术称为南瓜坐骑，以及3D协作工具Konteru。现在，除了在TTWIIN计划中工作外，还有五家公司。

斯卡兰格洛说，在桑顿·托马塞蒂（Thornton Thomasetti）内外，推出TTWIIN刺激了创新投资。该公司的第二轮IP工具针对商业化的IP工具始于2020年，其名称为TTWIIN 2。它包括T2D2，T2D2是一个AI软件平台，可检测和分类对立面的可见损失。
