• Thermal engineering = one discipline in the product development process

• Increasing need for integrated multi-disciplinary engineering process

• The need for open standards

• Where are we with STEP-TAS?

• Link with the technology harmonisation

• What may be expected next?

• The global competitive market demands:� Shorter time to market� At lower development and operation cost� While maintaining high quality and reliability

• Focussing on the contribution of CAE to the product development process …

• Today complex analysis and simulation tasks can be performed adequately by all individual engineering disciplines

• Looking at the overall product development process the next level of efficiency improvements must come from an integrated multi-disciplinary engineering process

• This does NOT invalidate all improvements for thermal analysis as discussed in this workshop, but …

• We need to think about how to best fit thermal analysis into an integrated multi-disciplinary process

• Since we cannot prescribe a single tool(set) for all system-levels, for all supplier-levels, for all disciplines, we need reliable, easy-to-use, open standards

• Data exchange

• Long term data archiving

• Application programming interfaces

• Trend: the major aerospace CAD/CAE vendors are creating "open CAD/CAE platforms"

• STEP-TAS standard for exchange and long term archiving of thermal analysis models and results

– As per policy endorsed by Harmonisation Steering Board– Support to development STEP-SPE sister standard (space environment)

• TASverter implementation and distribution– Knowledge transfer to thermal analysis tool developers

• Converter from CAD (STEP 203/214) to STEP-TAS with automated simplification– Contribution in kind to BagheraView viewer developed under CNES funding

• expressik (open source STEP/EXPRESS Interface Kit)• Participation in ECSS standards development

– ECSS E-10 Part 7 "Product data exchange" (published November 2004)– ECSS E-10 Part 9 "Engineering database" (in progress)– ECSS E-10 Part 13 "Modelling and simulation" (in progress)
