Flowmaster Ltd. was a leading British Engineering Simulation Software company based in Towcester, UK. Its flagship 1D CFD product, also named ‘Flowmaster’, was first released commercially in 1987 although initial versions went back to the early 1980s having originated from BHRA, the not-for-profit British Hydromechanics Research Association, later to become the BHR Group. Flowmaster 1D thermo-fluid systems simulation software employed a matrix type solver and was the first tool of its type onto the market. It was initially sold and marketed by Amazon Computers Ltd based in Milton Keynes, UK. The software covered many different industries such as aerospace, automotive, marine, oil and gas, power generation, process, rail and water. Flowmaster software itself was based on extensive experimental validation data from D. S. Miller’s internationally respected scientific textbook, ‘Internal Flow Systems’, first published in 1978. A company called Flowmaster International (that later became Flowmaster Ltd) was created in 1992 when Richard Tickle was appointed CEO. During the next ten years Flowmaster experienced significant growth opening international sales offices near Frankfurt, Germany and Chicago, USA. Richard was followed as CEO by Alan Berry who led the company up to its acquisition in 2012 by Mentor Graphics Corporation where it became part of Mentor’s Mechanical Analysis Division. The Flowmaster product has subsequently been renamed as FloMASTER by Mentor Graphics in 2016 for its V8 release. Following the acquisition by Siemens Digital Industries in 2017, FloMASTER became part of the Siemens Digital Industries Software offering. Now part of Simulation and Test, FloMASTER goes to market as Simcenter Flomaster. History Development work first commenced on a commercial computer code that would become ‘Flowmaster’ in the period between 1980 and 1984 based on the extensive BHRA research data from Don Miller’s ‘Internal Flow Systems’ for pipework and ducting. Flowmaster V1.0 was subsequently released commercially in 1987. It was the first general purpose 1D CFD flow solver, having ‘pick and drop’ components and an interactive user interface with “joystick” control; all innovations for their time. Its first customer was Vickers Shipbuilding and Engineering Ltd. in the UK. By 2002, the 1,000th commercial license of Flowmaster was purchased by Tokyo Gas Company Ltd. Flowmaster V1 was released in 1987. Flowmaster V2 was released in 1990. Flowmaster V3 was released in 1993. Flowmaster V4 was released in 1995. Flowmaster V5 was released in 1997. Flowmaster V6 was released in 1999. Flowmaster V7 was released in 2007. FloMASTER (Flowmaster)
