The post-processor (AVL Impress) remains the standard, but the workflow has changed:
Compare the results ( .res file) with the results from the previous version. Slight differences are normal due to improved solver precision, but major discrepancies should be investigated. 5. Troubleshooting Common Update Issues

Start by placing the Cylinder component. This is the heart of the simulation where combustion occurs. You must define the cylinder geometry, including bore, stroke, and compression ratio. Next, add the Intake and Exhaust Valves. For an accurate model, you need valve lift curves and flow coefficients, which are typically determined through flow bench testing or CFD analysis.
Check for valve overlap, pumping losses, and scavenging efficiency. Emissions Report: Review NOxcap N cap O sub x CO2cap C cap O sub 2 , and soot levels in the results file.
