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

1st experiences

• T ENT is running with/on HP workstation network• S pecial problems with software

implementations/vers ions have been resolved• T est phase is running• Further development is necessary for adaptation to

Airbus needs• S pecification of requirements is ongoing process

T E NT is a practical bas is for the development of anoverall software sys tem for the automated use of

complex CFD

Work flow management: contextual cons iderations• What is the importance of s tandardisation?

- CORBA, JAVA- Independence on hardware/operating systems, etc.

• Can we solve the problem with different approach?- mask driven tools communication via files (AS CII)

like PointerPro• What about integration of PDM and data bank

systems?- Windchill or others- ORACLE

• Who will provide comprehens ive service?- Necessary for all-day-working tool!

• Why is T E NT a leading tool?
