In this workshop we will discuss timely and popular topics in internal combustion (IC) engine modeling and some of the unique features of CONVERGE that yield efficient and accurate simulations. Ever wonder why predicted cylinder quantities do not match the measured data when you think you have set up the case correctly? We will talk about what you need to consider when the predicted cylinder pressures do not agree with measurements and how to assess the accuracy of your input parameters. With optimized cell counts via Adaptive Mesh Refinement and fast flow and detailed chemistry solvers, you can extend your simulation domain to include multiple cylinders to analyze cylinder-to-cylinder variation, run multiple cycles to understand cycle-to-cycle variation, and capture propagating pressure waves to resolve engine knock. We will draw case setup recommendations from published works that use CONVERGE.*This lecture includes hands-on CONVERGE Studio practice.
