See Caedium Product Comparisons for prices and a feature list 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 a custom version of OpenFOAM®1 to provide 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 SimulationCaedium 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.

OpenFOAM 1.7.x on Windows 64-bit with Native MPI

We have updated our Windows patch for the latest OpenFOAM® release (v1.7.x). As with the previous patch version this also supports 64-bit compilation using the MinGW-w64 cross-compiler and parallel computation using the native Windows MPI implementation provided by the free Microsoft HPC SDK and also available on Microsoft Windows HPC Server 2008 for clusters.

Screencast of Flow Through a Pipe into a Box

This screencast shows how to use Caedium Professional to create the geometry and simulate a steady-state turbulent CFD simulation of air flow through a pipe into a box. Also you will see how to create velocity vectors and particle tracks within the flow volume and monitor residuals as the simulation converges.

August 2010

Phew, what a month! We have just released a new version of Caedium that is capable of performing both faster and larger CFD simulations than ever before. We've updated all our RANS Flow tutorials to reflect more robust default solver settings, and we've added some new tips to help you simulate faster and better than ever. All that's left for me to do now is get out of your way and let you enjoy it.

Faster CFD as Caedium goes Parallel

The latest release of Caedium (v2.2) can now perform Computational Fluid Dynamics (CFD) simulations in parallel on a single computer with multiple cores or on a cluster running Microsoft Windows HPC Server 2008 - either way it means a significant reduction in simulation turnaround time compared to previous versions of Caedium. Also available with this release are 64-bit versions of Caedium for Windows and Linux, which can perform much larger simulations since they are no longer restricted by the 32-bit memory limit.

Introducing Flexible Caedium Subscriptions

Caedium subscriptions are now available per month, per quarter, and per year for small businesses and hobbyists to perform Computational Fluid Dynamics (CFD) simulations as needed. The new subscriptions bring CFD within the budget of anyone who wants to join the virtual simulation revolution.

New Australian F1 in Schools Champions Helped by Caedium

Computational Fluid Dynamics (CFD) simulations performed using Caedium Professional helped Basilisk Performance become the 2009 F1 in Schools Australian National Champions. The air flow simulations provided 3D visualization of pressure and velocity, along with drag and downforce values. Chief designer Brett Sizeland then used these results to guide the aerodynamic design of the team's CO2 dragster in order to minimize its drag and deliver a well earned victory.

Open Wheel Race Car CFD Analysis

Open wheel race cars, such as those found in Formula 1 (F1), are characterized by complex aerodynamics. With geometry preparation, meshing, physics setup, solver control, and results extraction all combined in a single unified simulation environment, Caedium Professional is a good choice for assessing the aerodynamic performance of such cars using Computational Fluid Dynamics (CFD).

Electric Race Car CFD Analysis

Many see the future of automobiles to be electric, so it's only natural to assume that the same may apply to motor racing. Luke Horsfall is one who believes electric race cars have a bright future, having set up Horsfall Racing (along with Laura Horsfall) to build electric race cars and race them in the F24+ electric race car class in the UK. The restrictions of this particular formula keep budgets and speeds relatively low (at least by Formula 1 standards). Making best use of the limited power in F24+ is crucial, and that places the emphasis on low-drag, aerodynamic race cars. I bet you can guess where this is heading - this is territory ripe for Caedium's Computational Fluid Dynamics (CFD) capabilities.

Caedium Brings Interactive CFD to the Mac

The latest release of Caedium (v2.1) now supports Mac OS X 10.5 (Leopard) and 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.
