Aachen, Germany – Santa Fe, New Mexico, USA, January 31, 2022

Dr. Flender Holding GmbH, owner of MAGMA Giessereitechnologie GmbH and SIGMA Engineering GmbH, acquired 100% of the shares of Flow Science, Inc. in December 2021.

The developer of the FLOW-3D family of products, Flow Science is a globally recognized and a successful provider of computational fluid dynamics (CFD) solutions for a wide variety of engineering applications. With its broad range of products and services, Flow Science will continue to operate as an independent company as part of the Dr. Flender Holding group. The mutually agreed acquisition ensures that all the management and staff at Flow Science stay with the company under the leadership of its current CEO, Dr. Amir Isfahani. Flow Science customers will see no changes or disruptions in their products, licensing, or workflows.

The best fit for our people, our customers, and our technology were at the heart of this agreement. This acquisition not only lets us maintain what we value the most, but also provides an exciting opportunity for us to grow our market share and accelerate our development through continued collaboration within the Flow Science group of global companies, as well as now with MAGMA and SIGMA’s talented teams, said Dr. Amir Isfahani, CEO of Flow Science. Our customers can expect an expanded product development pipeline as well as the same best-in-class support that we have always strived to deliver.

Overall, there is a significant potential for synergies between the group of companies, especially in product development but also in marketing and distribution. Continuous and targeted improvements to the existing product portfolio and the development of new product offerings through the expanded team of experts are at the core of the strategy for this acquisition.

We were always impressed by Flow Science as one of the pioneers in the CFD industry as well as the level of innovation and competition that they have brought to the market for over 40 years. For us, this acquisition strengthens our presence in the market and opens new doors for us in other markets and application areas, said Dr. Erwin Flender, Owner of Dr. Flender Holding GmbH.
