Lessons in CFD from 2016

In our second review post for 2016, here are lessons and guidance to make your Computational Fluid Dynamics (CFD) more productive in 2017. "Those who do not learn [from] history are doomed to repeat it."

Turbulence Model Selection

Most CFD software provides an array of turbulence models. Knowing which model to select is not always an easy decision given trade offs between accuracy and computing requirements. Read more >>

Symmetry for CFD to the Rescue

Symmetry is a simple but powerful concept that you can use to speed up your CFD simulations and reduce your memory requirements. Join me in an exploration of a simple symmetry case. Read more >>

Never Settle For Facets

Don't settle for CFD software that uses (abuses) facets (e.g., STL) as geometry. If your original geometry is analytic (CAD) then mesh it directly without the conversion to facets. Otherwise it's like you have to create two surface meshes. What's wrong with that? Plenty! Read more >>

When Good CFD Goes Bad

You've checked everything, and I mean everything, but still your CFD simulation does not resemble reality. Then it's time to consider the deeper underlying basis of your CFD software. Read more >>

Cutting Planes Reveal Yet More Hidden CFD Secrets

Yet another way to reveal the hidden secrets of your CFD simulation is to create a face, usually a plane and often referred to as a cutting plane, to serve as a target for interpolated results. Read more >>

Clipping Planes Reveal Even More Hidden CFD Secrets

Clipping planes are another tool to reveal hidden regions of your CFD results. Read more >>

Symmetry Reveals More Hidden CFD Secrets

Following on from "Transparency Reveals Hidden CFD Secrets," using symmetry is another way to reveal the hidden secrets of your CFD simulations. Read more >>

Transparency Reveals Hidden CFD Secrets

Do you find that visual elements in your CFD simulations sometimes obscure the areas where you would like to see your results? If so, then let transparency reveal the hidden secrets within your results. Read more >>

Results Setup For CFD

Before you press the run button for your CFD simulation you should configure your results to provide feedback on the simulation's progress. In most modern CFD systems, such as Caedium, you can use co-processing to update your results simultaneously while your CFD simulation runs. Assuming you have the option to co-process your CFD results then here are some helpful tips on how to proceed. Read more >>

CFD for Your SMB

Being a small business ourselves we understand that one of the key issue that drives many Small-to-Medium-sized Businesses (SMBs) is efficient resource allocation. For CFD simulations, our area of expertise, that means the SMB wants their needs precisely met in terms of pricing, features, and support. To address these issues, Symscape offers flexible duration subscriptions to Caedium that include support and various bundled features in Caedium add-ons. There are no initial sign up fees and no re-sign up fees. Read more >>
