1.1 Bounded-constrained gradient optimization of a blunt body

Blunt body with control points. Initial shape.

Shape optimization of the blunt body

• In this short tutorial we do a bounded-constrained gradient optimization study of a blunt body.

• We aim at optimizing the shape of a blunt body. The goal is to minimize the drag coefficient.

• The body is parametrized using Bezier curves with four control points and six linear constraints.

• To do the optimization we use Dakota, Salome and OpenFOAM. The geometry and mesh are generated with Salome.

• This tutorial works fine with OpenFOAM 2.3.0, Salome 7.3.0 and Dakota 5.4.0.

• Before running the tutorial, execute the script dakota_cleanup.
