Day 1: Foundations of CFD & Pre-Processing

• Morning Session: Introduction to Industrial CFD. The workshop began with an industrial lecture on the role of CFD in modern aerospace, automotive, and energy sectors. Students gained an appreciation for how CFD improves component performance and efficiency.

• Afternoon Session: Hands-on with Geometry & Mesh Generation. Participants were introduced to the principles of grid generation. They learned about different mesh types and the importance of grid convergence, a key factor highlighted in international workshops for achieving accurate results. Students practiced creating computational domains for benchmark problems.

Day 2: Solver Theory & Simulation Setup

• Morning Session: Understanding Solver Settings. This session covered the theoretical aspects of solvers, turbulence models, and numerical schemes. Discussions included the capabilities and limitations of Reynolds-averaged Navier-Stokes (RANS) simulations, which remain the prevailing industrial method. Reference was made to major AIAA workshops to illustrate the importance of best practices.

• Afternoon Session: Running Simulations. Students set up and executed their first simulations. They learned to monitor convergence and adjust solver parameters, gaining "firsthand experience of solving problems using CFD".

Day 3: Advanced Topics, Result Analysis & Validation

• Morning Session: Post-Processing & Validation. Participants learned to analyze simulation results, generate reports, and visualize flow patterns. A critical component was teaching students how to validate their results against experimental data, mirroring the processes used in international prediction workshops.

• Afternoon Session: Project & Valedictory. Students worked on a project, such as analyzing flow over an airfoil or through a pipe bend. The workshop concluded with a valedictory session where students presented their findings and received certificates of participation.
