While marginal gains are all the rage in cycling, US trucks by comparison are a target rich environment when it comes to external aerodynamics. Specifically the name of the game in haulage is to minimize fuel costs and that translates directly to minimizing drag.

The next release of the Caedium CFD software system will be able to simulate Conjugate Heat Transfer (CHT). CHT models the heat transfer due to conduction through a solid or shell, coupled with fluid convection at shared boundaries.

Before you press the run button for your Computational Fluid Dynamics (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.

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 Computational Fluid Dynamics (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.

A Computational Fluid Dynamics (CFD) simulation requires that you configure physics and solver values based on your knowledge of your fluid application. Primarily this setup stage requires defining your fluid state, reference values (e.g., velocity), initial values, boundary conditions, and solver parameters. Follow along as I describe each stage and relate it to a CFD simulation of the external airflow over an idealized car.
