3. Loop optimasi DAKOTA-OpenFOAM | Optimasi berbasis gradien

In this video we walk through the gradient‑based optimization of a blunt body shape using DAKOTA and OpenFOAM. We start with an introduction at 00:00, discuss the case basis at 00:45, remind the audience of the process at 03:20, explain DAKOTA output format at 06:24, note documentation at 08:40, show input files at 09:40, script details at 18:20, launch the optimization at 25:20, present the final solution at 30:00, post‑process at 33:20, manipulate data with Bash scripts at 38:24, review input and output files at 40:20, give final notes at 40:44, clean up the case directory at 42:42, and cover script execution permissions at 43:25. The workflow uses Salome for geometry and mesh generation, OpenFOAM 11 as the black‑box solver, DAKOTA 6.19.0 for optimization and orchestration, and Bash/Python scripts for automation and post‑processing.
