The document discusses virtual reality and real-time simulation capabilities at the National Institute for Aviation Research. It describes the facility's visualization room and notable equipment, including large field-of-view head-mounted displays, PC clusters, and software like CATIA and Virtools. The approach uses CATIA for modeling, materials, and ergonomic analysis. Virtools enables behavioral simulations. OPTIS SPEOS is used for visual ergonomics and illumination analysis. Real-time simulations examine interior layouts, materials, and human factors analysis.

The anthropometric parameters can be exposed if in the Anthropometric List Dialog the Management field is setup to
manual. This means that it’s possible to have User Defined parameters associated with Knowledgeware (Formulas,
Rules, Reactions, etc…) for variations on interior layout. In addition, manikin’s end‐effectors can be constrained to
CATParts in DMU Fitting Simulator or Kinematics. This can be useful in real‐time simulations of accessibility,
line‐of‐sight and posture.

manufacturing each part is unique located in their final
assembly even if the selected part is not unique in shape and
function. Future code will require Artificial Intelligence
