Best Free Simulation Software of 2026

DigitalClone®, for Engineering is the only software that integrates multiple scales of analysis into a single package. It is the world's best gearbox reliability prediction tool. DC-E, in addition to the modeling and analysis capabilities at the level of the gearbox and the gear/bearing, is the only software that models fatigue life using detailed, physics-based models (US Patent 10474772B2). DC-E allows the construction of a digital twin of a gearbox. This includes all stages of the asset's lifecycle, from design and manufacturing optimization to supplier selection to failure root cause analysis to condition based maintenance and prognostics. This computational environment reduces the time and cost of bringing new designs to market and maintaining them over time.

FlexSim allows you to answer any question about your company with accuracy. It is a powerful simulation tool that was built from the ground up to make simulation simple and easy without sacrificing any functionality or visual appeal. With drag-and-drop controls, easy-to-use features, you can create stunning, detailed models that produce results but make an impact like charts or spreadsheets.
