An Object-Oriented Parallel Multidisciplinary Simulation System - The SimServer.

Publisher Summary This chapter discusses object-oriented (OO) approach for a parallel multidisciplinary simulation environment, the SimServer-system. It has been designed for aerodynamic problems solved by the application of nonlinear computational fluid dynamics (CFD) methods based on the Euler and Navier-Stokes equations on unstructured hybrid grids. The OO design and implementation of the system, the top level components and the integration of existing parallel CFD solvers are illustrated. A novel modeling approach for the execution of a mono- or multi-disciplinary simulation via events is demonstrated. Important parallelization aspects based on the message passing paradigm are highlighted and the advantages and limitations of the presented concepts are discussed. Additional incorporated coupling algorithms in space and time are described, supporting both strongly coupled aeroelastic calculations and transient aerodynamic simulations strongly coupled to flight mechanics with up to six degrees of freedom. Finally, the presented multidisciplinary examples demonstrated the capabilities of the system.
