Decarbonising the global transport sectors is critical to creating sustainable mobility fit for the future.

Realis Simulation, formerly Ricardo Software is a trusted partner to the world’s leading transport manufacturers, OEMs, and Tier 1 suppliers. We enable rapid software modelling of new propulsion fuels and technologies, supporting the journey to net zero emissions - quickly answering the ’What ifs?’. in a fast, predictable and cost effective manner. Our simulations provide results which enhance transportation development at a time when engineering resources are tighter than ever before. The suite of leading edge simulation tools facilitates design and optimisation programmes as we transition into the future whether that be New Fuels for Internal Combustion Engines, Hybridisation, Electrification or Hydrogen and Fuel Cell technology.

Accelerating Possibilities

Our mission is to continue enabling expert design engineers to model propulsion technologies fit for the future. Realis engineering analysis tools deliver rapid results for fluids, structures and systems which empower our customers to address the planet’s biggest transport decarbonisation challenges. Based on nearly 30 years of software expertise, Realis focuses on delivering highly tailored tools to provide fast, repeatable and predictive results across existing and emerging technologies.
