Novel Features:

  • Creation of simulation software by combining individual simulation processes
  • Inclusion of information agents in simulation process
  • Provision of distributed environment
  • Automatic model refinement

Approach

  • CAD models enhanced with cross-disciplinary engineering analysis and behavior models
  • Transparent composition of simulations inenhanced CAD
  • Hierarchical distributed simulationarchitecture
  • CORBA-based implementation

System Overview

Component Models:

  • Object-Oriented Modeling Paradigm -- reuse of models
  • Design Repository used to select CAD compoments -- incorporates ADAMS or DADS
  • Information Agents -- control sytem algoirhtms, environment definition

Software Architecture

  • Analyze conceptual graph to create simulation processes
    • distributed objects
    • retrieve CAD information via ACIS
  • Build simulator architecture
    • synchronization mechanisms
    • communication protocols
  • Execute simulation

Impact
