The Ansys Forte CFD^™ software is designed for 3-D, multi-phase engine simulations with combustion. This manual consists of tutorials that illustrate how to use Ansys Forte CFD to address a variety of engine designs including compression ignition and spark ignition. The tutorials generally represent realistic situations that might be encountered by practicing scientists or engineers. They have been chosen to demonstrate the wide range of software capabilities, and the different ways Ansys Forte can be used.

In this manual, we address major types of engine simulations: Diesel modeling with sector mesh generation is covered in Simulating a Diesel Engine Using a Sector Mesh, modeling of Dual Fuels is covered in Simulating Dual Fuel Combustion, Evaporating Spray modeling is covered in Spray Bomb Modeling, and Spark Ignition modeling with moving valves, and automatic mesh generation in Port-Injected Spark Ignition Engine. Soot particle tracking is demonstrated in Tracking Soot Particles Evolution in a Diesel Engine. In Gasoline Direct Injection Engine Simulation, gasoline direct injection in an SI engine is modeled. A compressor is described in Rotary Lobe Compressor Simulation. The Built-in FSI feature is employed in the examples in Piston Compression Pump With Built-in FSI and Valved Pulse-Jet With Built-in FSI. FSI combines with Ansys Mechanical via System Coupling in Oscillating Plate FSI Using System Coupling. System Coupling is also employed in System Coupling CHT for T-junction Pipe Flow, Conjugate Heat Transfer Simulation of a Single-Cylinder Internal Combustion Engine, and Generic Full-cycle Diesel Engine CHT Using System Coupling. FSI is featured with UDFs (User Defined Functions) in Two-Stroke Full Engine Simulation with UDF for Connecting Rod Motion.

In Two-Stroke Engine Simulation, a two-stroke marine engine with intake and exhaust ports is described. This lesson also includes a restart file, pressure profiles, plus an .stl file, to try starting from only the geometry. A similar two-sroke case worked with User Defined Functions (UDF) is available in Two-Stroke Full Engine Simulation with UDF for Connecting Rod Motion. A four-stroke engine is modeled in Multi-Cylinder Four-Stroke Engine Simulation.

Pumps and compressors are explored in Piston Compression Pump With Built-in FSI, Generic Gerotor Pump, Rotary Lobe Compressor Simulation, and Scroll Compressor Simulation, and Screw Compressor Simulation.

System coupling with Ansys System Coupling is covered: a simple case in System Coupling CHT for T-junction Pipe Flow and a single-cylinder engine CHT analysis with coupled thermal analysis from Ansys Fluent in Conjugate Heat Transfer Simulation of a Single-Cylinder Internal Combustion Engine and a diesel engine CHT analysis appears in Generic Full-cycle Diesel Engine CHT Using System Coupling. System Coupling unites interfaces between Ansys Forte FSI and Ansys Mechanical in Oscillating Plate FSI Using System Coupling.
