Design Optimization with Cart3D

Optimization aerodynamic design of a vehicle is challenging. Optimization with CAD geometry in an automated loop is even more challenging. CAPRI is enabling engineers at NASA to perform thousands of Cart3D design studies with parametric CAD models.

CAPRI provides the key ingredients to make this possible.

  • Hands-off geometry transfer from CAD to Cart3D
  • Permits simulation code to drive parametric changes in the actual CAD model
  • Very high reliability in generating watertight components for design variations
  • Distributed computing architecture to support optimization in a heterogeneous computing environment



"We have performed over 10,000 automated CFD design iterations using CAPRI for CAD integration, with parametric update and surface wrapping reliability exceeding 99.98%."

Cart3D Design Application

NASA uses CAPRI for CAD-based design optimization of supersonic aircraft. The recent application illustrates a powerful application of CAPRI to perform shape design directly in CAD.
