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: material)

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. […]

Pushover notifications for STAR-CCM+

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 […]

Actually, think, feel

Having quantitated what is actually happening as opposed to what engineers think should happen and what the driver feels is happening, it should then be possible to study […]

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 […]

Physic models in STAR-CCM+ (Part I)

Now that we’ve seen the meshing models available in STAR-CCM+, it is about time to have a look at the physic models solvers used to provide […]

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 […]

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 […]
