"Over the past 20 years the market has clearly validated our approach of embedding powerful simulation software into the heart of our customers' design processes," said Dr Mike Reynell, Director of Marketing. "The key is to make simulation software easy to use for the people with the responsibility for developing innovative products and processes that drive their own companies' success."

Company founders David Tatchell and Harvey Rosten first worked together in the 1970s pioneering the commercial availability of CFD technologies, and in 1988, founded the company to develop CFD software to simulate thermal exchange for pre-prototype product development. Tatchell served as CEO until his retirement in 2006. Rosten led the development effort for the company's first products. He passed away 1997.

The company's first product, Flotherm, used in thermal design for electronic systems, was launched in September 1989. The company's second product, Flovent, used to optimize building heating, ventilation and air conditioning systems was released in early 1990. In 1995 the company went public, listing on the London Stock Exchange Alternative Investment Market.
