## I hereby declare you guilty

The judicial presumption of innocence does not hold in CFD. CFD results are wrong, until proven otherwise —Bert Blocken.

## Grid sensitivity analysis on the front wing of the McLaren MP4-29 F1 race car

An important aspect to take into account when pushing for a good Computational Fluid Dynamics simulation is the process of verification and validation. Validation is usually carried […]

## Computational study of the flow around the Ahmed vehicle model

The Ahmed vehicle model was introduced in 1984 by Ahmed et al. [1] to investigate the flow structure on the drag in the automotive industry. […]

## Drag Reduction System (DRS)

Wanting to get some in depth knowledge about competition car aerodynamics, the performance of a Drag Reduction System DRS should not pass unnoticed. In the […]

## Physic models in STAR-CCM+ (Part IV)

We can find turbulence every day in almost every daily situation, whether it be smoke from a cigarette, water in a river or waterfall, the […]

## Physic models in STAR-CCM+ (Part III)

When the Knudsen number $$Kn = \frac{M}{Re}\sqrt{\frac{\gamma \pi}{2}}$$ is small, Kn < 0.01, the continuum mechanics formulation of fluid dynamics is valid, and so are […]

## Physic models in STAR-CCM+ (Part II)

We’ve already discussed space, time and motion models, which represent just a small portion of the physic models available in STAR-CCM+. This is Part II. […]

CFD simulations are usually lengthy, very lengthy, and we don’t want to spend time looking at a screen again and again to see whether the […]
