1.1 Bounded-constrained gradient optimization of a 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.
- File:Blunt body case.zip. Inside the README.FIRST file, you will find the instructions of how to run the case.
