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: turbulence models)
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 […]

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 […]

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 […]

Memory upgrade
Although for daily usage 2 to 4 GB of RAM may seem sufficient, when it comes to CAE, all that memory space is soon swallowed […]

Dyson’s Air Multiplier with STAR-CCM+
As I mentioned in a previous post, I was curious about how Dyson’s Air Multiplier worked. There is a quite interesting video in YouTube where […]

Mesh models in STAR-CCM+
As it is very important to stablish a proper grid resolution before attempting to solve any CFD problem, I’ll try to analyse the different mesh […]
Continue reading »Grid resolution
CFD solutions are typically more sensitive to grid resolution than the turbulence model and convective flux discretization, so it is recommended to establish proper grid […]
