About Us

TotalSim-CFD is the CFD consultancy within the TotalSim Group of companies. Born out of the restructuring of the TotalSim Group in 2021/22, we retain the core CFD modelling capabilities developed within TotalSim since 2007. We deliver top-level CFD consultancy as well as being able to support your in-house CFD needs.


TotalSim has had CFD at its core since its formation in 2007, when Rob Lewis and six others left Advantage-CFD, owned at the time by Honda F1, to operate independently following Honda’s decision to move away from external consultancy.

The growth, diversification, and inevitable restructure of what has now become the TotalSim Group of companies led to the formation of TotalSim-CFD. We are still led by Rob Lewis, with original TotalSim founders Matt Cross, David Ludlow and Graham Martin remaining in key roles within TotalSim-CFD, and joined by the talented team around them.

TotalSimCFD racks up well over 100 man-years of direct CFD experience, and is also able to collaborate and work seamlessly with the other companies within the TotalSim Group, including Bramble, Catesby Projects, Catesby Tunnel, Silverstone Sports Hub and Vorteq, to form a formidable engineering capability. We also work closely with our international partners, TotalSim US and TotalSim Japan, to give a global spread.
