The Truck Add-on Predictor was developed under a collaborative effort sponsored by the Department of Energy and managed by the National Center for Manufacturing Sciences. Collaborators included the Ohio Supercomputer Center, TotalSim, SimaFore, and Nimbis Services. The Truck Add-on Predictor allows suppliers unfamiliar with computational fluid dynamics (CFD) to model the airflow over a joint vehicle / trailer body and the corresponding aerodynamic forces generated on the trailer, tow vehicle, and combination. By understanding the forces on the various surfaces of a trailer, trailer designers and part suppliers can reduce the weight of key structural components, replace them with other materials, or utilize novel shapes that are required for special materials while potentially increasing the aerodynamic efficiency of the trailer. The CFD calculations are performed using TotalSim’s optimized version of OpenFOAM, an open source CFD software package.
The Startup Package: All new users of the Truck Add-on Predictor will begin with the Startup Package. The Startup Package is a low-cost, low-risk, entry-point solution for new users unfamiliar with the use and application of the Truck Add-on Predictor. The package includes 5,000 core hours of compute time at the Ohio Supercomputer Center (OSC) and eight hours of OSC technical support in the use of the application including use case analysis, problem configuration, and job results analysis and interpretation. The duration of the service is 90 calendar days from the date your order is placed. Job sessions are opened and controlled entirely through your account dashboard in your web browser.
The price includes 5,000 core hours of compute time and eight hours of technical support by email and phone. The service begins when the order is placed and ends after 90 calendar days.
