Overview of Open SimDM SimDM Program Objectives Use cases Product Functionality Open SimDM Architecture Pilots and Dissemination Conclusions

SimDM Program Objectives Improve the effectiveness of simulation and analysis programs and the sharing of the information produced Simulation data will be made accessible for the support and upgrade of aircraft, land vehicles, and ships: Allows users such as national Ministries of Defence and Air Logistics Centers to have access to simulation information. SimDM will interface with off-the-shelf CAD and CAE engineering applications: Provides the mechanisms for single access to product structure, CAD models, and CAE simulation data of engineering programs. Long term data retention issues will be resolved by using the internationally-recognized ISO 10303-209e2 STEP standardized format: Enables cost-effective life-cycle processes.
