0. Coupling DAKOTA 6.19.0 with OpenFOAM 11 | A simple CFD optimization test case

Description:

🫡 Short demo of how to couple DAKOTA with any black-box solver. In this case, we are using OpenFOAM 11 as a black-box solver and a lot of bash scripting. As a demo case we use the driven cavity validation case. 🤖 DAKOTA optimization toolbox In this demo case, we use the following tools: - Mesh generation: OpenFOAM 11. - Balck box solver: OpenFOAM 11. - Automatic post-processing: bash scripting and Python. - Plotting: Python. - Optimization and orchestrating tool: DAKOTA 6.19.0 00:00 Coupling DAKOTA 6.19.0 with OpenFOAM 11 02:45 Let's start - DAKOTA crash introduction 07:45 Workflow for data exchange between DAKOTA and a black-box application 08:45 Presentation of the test case 12:42 Let's run the case - Parametric case 28:17 Let's run the case - Gradient-based optimization case 39:30 Final remarks 40:21 Small philosophical reflection regarding AI/ML in CFD - Let me criticize the use and abuse of AI/ML in CFD - You can skip this part Compressed tutorial: - Driven cavity case Deck of slides: - DAKOTA crash intro Related playlists: - Transitioning to OpenFOAM 11 from OpenFOAM 10/9, - DAKOTA optimization toolbox | Explore and predict with confidence | Installation and getting started, - OpenFOAM in Windows Subsystem for Linux (WSL) | Wolf Dynamics WSL virtual machine Software links: - - - - - - - Additional links: - Excellent reference for optimization methods, - Mixed-Integer Parallel Efficient Global Optimization 👍 CFD optimization and automation. 👏 Engineering design optimization loop. ********************************************************************************** Wolʇ Dynamics, your reliable partner for CAE solutions, CAD and solid modeling → Meshing → Simulations → Automation and optimization → Post-processing → Data analytics and ML → Reporting Why Wolʇ Dynamics?
