The Heterogeneous Transformation Challenge

Homogeneous: Mapping between similar entities.
Example: part geometry in AutoCAD <---> part geometry in IDEAS

Heterogeneous: Mapping between disimilar entities.
Example: part geometry, assembly, material, etc. <---> finite element model
Example: part geometry, tooling knowledge <---> injection molding tool

DAI as a Heterogeneous Transformation

• Example: part geometry, material, environment <---> finite element model
• Transformation is design-analysis associativity.
• Forward form: idealization process (modeling)
  • Not 1:1
  • Requires analysis expertise
• Reverse form: synthesis process (design)
  • Not 1:1
  • Requires design expertise.
• Need explicit representation of design-analysis associativity itself.
