In late 1997, Rob left FLUENT to start AdvantageCFD (A-CFD) with Adrian Reynard at Reynard Motorsports. A-CFD supported all of Reynard Motorsports designs from Champ Car to the BAR F1 cars. Rob grew the A-CFD organisation to 25 people by late 2006 when it was an essential part of Honda F1 aerodynamics department. AdvantageCFD succeeded in setting the standard in motorsport CFD from inception to its closure in 2007. The switch in focus away from any outside consulting by the Honda F1 Racing Team gave Rob and some of the team at A-CFD the chance to continue working with their clients by creating TotalSim Ltd.
