Caedium

Our free Caedium download provides a unified simulation environment for Computer-Aided Engineering (CAE) that is easy to learn and fun to use. Whether your favorite operating system is Windows, Mac OS X, or Linux, Caedium has you covered with its unique native cross-platform architecture.

Caedium In Action

Use this free package to share 3D Computational Fluid Dynamics (CFD) simulation results for interactive viewing. Caedium supports multiple simulations, multiple 3D views of a simulation, and up to 4 camera angles of a view.

Expand Caedium's capabilities by purchasing affordable subscriptions to Caedium add-ons. All the Caedium add-ons seamlessly interact within the same unified simulation environment.

See our Caedium Product Comparisons for pricing and a detailed breakout of each add-on.

Caedium Professional

For a complete concept design analysis system, consider our Professional add-on, which combines all our add-ons at a discounted price.

Caedium RANS Flow

Our Caedium RANS Flow add-on uses state-of-the-art Reynolds-Averaged Navier-Stokes (RANS) flow solvers capable of simulating realistic, viscous fluid flow and heat transfer over and through virtually any configuration. Application examples include the external flow over a wind-turbine, aircraft, car, or a submersible, or the internal flow through a computer case, mining drill, pipe, or duct.

Caedium RANS Flow Simulation

Our seamless integration of advanced 3D visualization techniques within Caedium such as streamlines, vectors, iso-surfaces and contours makes it easy to extract and share stunning fluid-flow images. 2D XY plotting is also an integral part of the RANS Flow add-on making it easy to compare results with other Caedium simulations or with imported results such as those from wind tunnel experiments.

Caedium Panel Flow

Simulate 3D airflow over racing cars or evaluate the aerodynamic performance of airplane wings and airfoils with respect to their lift and form drag forces using our Panel Flow add-on. This add-on uses a panel method that assumes idealized, inviscid flow to rapidly solve surface-based potential-flow equations. Panel methods are ideal for analyzing subsonic fluid flow (e.g., air, water) over streamlined shapes such as cars, airplanes and submarines.

Caedium Builder

Create your own geometry or modify existing designs using our 3D solid modeling, NURBS-based Builder add-on. Using advanced Boolean operations such as unite, subtract and intersect, rapid geometry construction is easy.

Caedium Transient

Simulate time-dependent flow with geometry motion using our Transient add-on. Then review your transient flow results in real-time using familiar multimedia-like controls.

Caedium Exchange

Import and export geometry in standard IGES (.igs), STEP (.stp) and faceted file formats using our Exchange add-on. Combine imported geometry with geometry created using our Builder add-on.

Caedium Viz Export

Create stunning photo-realistic images using lights and shadows for fun or marketing with our Viz Export add-on that exports POV-Ray (.pov) and Renderman (.rib) file formats. Also share 3D views in standard Alias/Wavefront (.obj) and VRML (.wrl) file formats with other visualization systems.

The latest release of Caedium (v2.1) now supports Mac OS X (10.6 Snow Leopard) in addition to Windows and Linux. Also in this new release are various enhancements to 3D selection, the properties panel, and geometry creation for all platforms.

Caedium on the Mac

After reviewing the Caedium RANS Flow results posted in "CFD Analysis of an F1 in Schools Dragster," Brett Sizeland, Basilisk Performance team's chief designer, has been busy updating his F1 in Schools CO2 dragster design. Using the same geometry preparation process, physics setup, and post-processing, all within Caedium's unified simulation environment, we were able to rapidly perform the new simulation and extract the flow results presented here.

We are back in full flight this month after last month's Florida trip - nothing like a New Hampshire winter to help you focus on work just to keep warm! For all those Apple fans out there - read about our progress towards a native Mac OS X version of Caedium. Also check out our Computational Fluid Dynamics (CFD) simulation of an F1 in Schools CO2 jet-powered dragster. And if that isn't enough, there's always the latest blog posts.

F1 in Schools is an international competition for student teams (aged 9-19) to design, analyze, build, and race CO2 jet-powered cars (dragsters). Beyond promoting Formula 1 (F1) to the next generation of fans, F1 in Schools aims to give a flavor of running an F1 team by exposing students to finance, marketing, and engineering. Of course the most exciting area (as in F1) is engineering, where students get to use state-of-the-art 3D CAD/CAM software to design and build their dragsters. Performance optimization through analysis of the dragster design is also encouraged, which inevitably leads to Computational Fluid Dynamics (CFD).

It seems like a short month, given the holiday season and my trip to Florida to present at the AIAA ASM conference. However, I did manage to jump back on the blog wagon with three posts this month. Read on for my trip report and my blog teasers.

It's been a blockbuster month full of action here since the big release last month. The headline news is that we renamed SymLab to Caedium - if you want to find out why and catch up with other developments, then keep reading.
