KIVA

KIVA is a specialized CFD code for simulation of internal combustion processes, multiphase flows, spray dynamics, and combustion chemistry in engines and propulsion systems. It couples turbulence, heat transfer, and fuel–air mixing models to predict performance, emissions, and transient behavior, enabling design optimization and testing across automotive and aerospace applications.

Key Advantages

• High-fidelity combustion and spray modeling with multi-species chemistry and detailed kinetics support for emissions prediction.
• Robust mesh and moving-boundary solvers for piston-cylinder, valve motion, and complex 3D geometries enabling transient engine simulations.
• Parallelized solvers and post-processing workflows for scalable simulations, parametric studies, and integration with optimization toolchains.

Professional Scope

Essential for Architects, Civil Engineers, Electrical Engineers, Interior Designers, Mechanical Engineers, and Surveyors – GIS Specialists when evaluating HVAC, energy systems, mechanical equipment, and site-level airflow or subsurface interactions requiring physics-based CFD insights.

Access & Licensing

Available as a free/open-source core for research and education, with paid-subscription cloud or enterprise editions for enhanced features and support, and paid-lifetime commercial licenses including long-term maintenance and bespoke integration.

Specialization
