Current manufacturing-oriented product model is less adaptable to subsequent numerical simulation. Toimprove transition efficiency between product geometry model and analysis model

product model representation in numericalsimulation phase has been analyzed. Then problems and requirements of analysis-oriented modeling have beensummarized before an analysis-oriented product modeling technique was proposed through improving parametric modelingtechnology. Finally

structure framework of the technique is constructed. To verify its validity

turbine blade models for differentnumerical simulations are generated

which reduce the difficulty of blade design and analysis integration. Other highqualitydigital models can take advantages from it.
