Page: 2 Simulation Data and Process Management. Topics. Basic Motivation. Current applications and Architecture. Coupling with other data management systems. Upcoming projects. numbers and benefits. @ BMW
Page: 3 Basic Motivation. The initial example scenario: Three engineers have to analyze the crash behavior of a virtual car model: ~10 mio DOF s. Same car model. Same crash load case. Compare the results in a report of 50 pages against the base line design. Within a week.??? External @ BMW
Page: 4 Basic Motivation. What could happen (in this example): Three engineers have to analyse the crash behaviour of a virtual car model: ~10 mio DOF s. Variation in small details Same car model. Not using the exactly same source data Same crash load case. Different formulation of load/functions and solving parameters Compare the results in a report of 50 pages against the base line design. Different Layout and content Within a week. Delay? @ BMW External
Page: 5 Basic Motivation. What could happen in real life: Not 3 but 400 engineers have to analyze the crash behavior of not one but 50 virtual car model?? External External External @ BMW External
Page: 6 Basic Motivation. What could happen in real life: Not 3 but 400 engineers have to analyze the crash behavior of not one but 50 virtual car model? Solution: Software with Business Logic for: Model Assembly and Sub model Definition. Data/Object Structure. Standard process to access current status of data. Standard process chain for pre/solve/post/report. to manage both the data and the processes. SimManager as the end to end solution. @ BMW

Page: 18 Upcoming Projects. Functional Mockup for Co Simulation. FMI. Simulation A Drive Line Dynamics FMI Simulation B Mechatronics Control System Specification of the Modelisar Activity. Hardware in the loop under investigation. Budget for SimManager Integration approved. @ BMW
Page: 19 Upcoming Projects. Real Time/Interactive Finite Element Simulation. Cooperation with TUM 3D Munich. Currently 60 fps/70000 hexa elements. Up to 750000 hexa elements with 2 fps Runs on nvidia s CUDA Engine. As Plug In for Design-, CAD, FE-Preproc tools. Budget for pilot approved. @ BMW
Page: 20 Upcoming Projects. Remote visualization integrated. No data exports/copy to review results or any 3D data. No local data anymore. Own environment for remote vis. close to HPC SimManager to dispatch visualization session from the web UI. No expensive user workstation necessary. Collaboration on one session for many users from different locations. @ BMW
Page: 21 Upcoming Projects. ADAMS Integration Out of the box solution will be installed. ADAMS and SimManager tightly connected. Exchange between MBS and FEA. @ BMW
Page: 22 Simulation Data Management. Summary: 280 users running up to 2500 Simulations per day. 80 Key Results and 1 Report created per Simulation. Users from 4 continents working with the same data sets. # of Engineers didn t grow over the last 4 years but the number development projects doubled. The planed increase of car project can be managed without increasing personnel resources. @ BMW
