CONVERGE™ Achieves Grid Convergence in Large Internal Combustion Engine Simulations
CFD simulations can be a powerful tool when designing an internal-combustion engine; however, the results of CFD simulations often change as the grid is refined. This is known as grid dependence. When grid dependence is observed, the traditional approach is to optimize the results by tuning grid sizes and model constants based on experimental data. This is a viable approach only in the presence of high-fidelity experimental data.
