Work flow management: Requirements (1)
• Individual set-up of process chains (work flownetworks)
• Process and data control through WFMS – interactiveand on demand
• Intelligent process control• Monitoring of running processes• S ystem to be run on heterogeneous platforms• Minimum effort integration of additional computational
tools• Integration of no-source-available codes• T raceability of runs• Automatic data management
19.11.01 Page 10

Work flow management: Requirements (2)
• Capability to run with job queueing systems• T o run on WAN/LAN• Cope with S S H/S CP restrictions• Distributed location of data• Distributed parallel run of contributing s imulation tools• Run robust with 99% reliability• Multi-user operation capability

B as ic approach: Component model
• Properties of components– Components have specific bas ic functionalities
and interfaces– For CFD process , we have at least 5 types of
components : Geometry Generation, MeshGeneration,F low S imulation, Postprocess ing and Visualisation
• Communication of Components– Realisation by CORBA (Common Object Request
Broker Architecture)– Exchange of data directly on network protocol
