Preparing Geometry for CFD

Preparing Geometry for CFD

No matter what CFD platform you are using, you will undoubtedly have to make CAD geometry ready for use in a simulation.  This guide details what is involved in preparing the geometry for bramble. For bramble, CAD needs to be turned into a triangulated mesh format...
How to Run an Aero-Map in CFD

How to Run an Aero-Map in CFD

After a competitive edge in your race-car aerodynamic setup? Building a lap-simulation?  Or wanting to understand how your vehicle’s performance varies in real world conditions?  Then an aero-map is an invaluable tool in your engineering arsenal. An aero-map provides...
The 64/4 Rule

The 64/4 Rule

In a recent article we covered how we went about migrating from a commercial CFD software package to OpenFOAM.  After discussing this further with a colleague, another interesting bit of learning came up – the Pareto Principle, otherwise know as the 80/20 rule....
The Humble Delta Cp Plot

The Humble Delta Cp Plot

When a simulation completes, we want to quickly determine what the effect of our test was. How have the forces and flow metrics changed, and perhaps more importantly, where and why have they changed? bramble produces a detailed set of forces, flow metrics and...
The 64/4 Rule

How We Adopted Open Source CFD

Back in the early-2000s some of our longer serving (older!) staff, myself included, were working at British American Racing.  For those who may not know, this was a Formula 1 team that would eventually transition into Mercedes F1. We were getting into optimisation as...
