Achieving Grid Convergence in Large Internal-Combustion Engine Simulations

Because grid-convergent internal combustion engine (ICE) simulations are computationally expensive,  high-performance computing (HPC) tools are necessary. HPC tools have  been used to simulate complex processes such as spray or combustion, but the full potential of HPC tools for engine simulations has not yet been realized. Motivated by the untapped potential of HPC tools for engine  simulations, personnel from Convergent Science Inc.; Caterpillar Inc.; and Argonne National Laboratory combined forces to carry out a series of engine simulations including a simulation of nearly 34 million cells that is believed to be the largest-ever diesel engine simulation. Read the story.
