Traditionally, SimulationbasedEngineering Sciences(SBES) made use of staticdata inputs to perform thesimulations. Namelyparameters of the model,boundary conditions, etc. weretraditionally obtained byexperimentation and could notbe modified during the course ofthe simulation. More recently,large efforts have been investedin developing dynamic datadrivenapplication systems(DDDAS): systems in whichmeasurements and simulationsare continuously influencingeach other in a symbioticmanner. It should be understoodthat measurements should beincorporated in real time to thesimulations, while simulationscould eventually control the wayin which measurements aredone.
