Advanced Simulation Software
for dynamic analysis of the complete powertrain and its components
Virtual Engine provides all building blocks needed to create dynamic models of powertrains including cranktrain, valvetrain, piston and rings, bearings, timing and accessory drive, geartrain, and driveline. Virtual Engine uses the core technology of the world-leading Multi-Body-Simulation Software MSC Adams® as numerical integrator, pre- and post-processing features. The template-based architecture perfectly combines the advantages of single-purpose software – ease of use and multi-purpose software – no limitations in extendibility. Virtual Engine is a truly open system – featuring a powerful scripting language for task automation, the ability to customize the user interface, support for own solver routines and extending the modeling component library with own user-defined elements. Wizards automate and accelerate the creation of complex models like crank and drive trains. Models and corresponding data are organized in databases, strengthening data management even for global scale companies. Advanced generic 3D contacts plus fast analytical approaches for powertrain-specific contacts ensure a vast scope of application.
From powertrain engineers to powertrain engineers: with its advanced simulation tool
Virtual Engine, FEV provides > in shorter time > low cost > high quality powertrain development.

- One environment for all analysis
- One model for all phases of the development
- Proven technology: fast, reliable, and validated
Unique Technology
The unique communicator technology and the template-based architecture support modular modeling.
From components to system-level simulation
Virtual Engine provides a modular modeling approach. One can build and analyze individual subsystems, which may consist of only one component or more. Virtual Engine is a so-called template-based product: every subsystem is derived from a template, which acts as a blueprint for the subsystem and defines its topology. Subsystems can be adjusted and refined to different fidelities as appropriate for the desired analysis. The unique communicator technology and the exceptional template-based architecture enable both modular and scalable modeling that correspond to both the user’s experience and the functional simulation demands. Using the communicator technology, a complete powertrain can be built with the subsystems and run as a fully coupled model.
Virtual Engine and Adams Car share the template-based architecture that perfectly combines the advantages of single-purpose software – ease of use and multi-purpose software – no limitations in extendibility. Given the same template-based architecture and communicator technology, Virtual Engine`s powertrain model can be directly coupled to Adams Car’s vehicle model and this complete powertrain and vehicle system-level model can be simulated dynamically.

High Quality Simulation
Rapid Low-Cost Powertrain Development
Cranktrain analysis
Virtual Engine supports modeling and simulation of all cranktrain types including inline, V-type, VR-type, W-type, or Boxer-type engines. Any type of cranktrain can be built in a few minutes using the Cranktrain Wizard, making it possible to create each component – from crankshaft to piston pins – on the fly. The resulting model as well as the individual parts can be refined in depth using rigid, torsional, beam, or fully flexible bodies. An integrated Gas Force Wizard allows the creation of gas pressure curves from basic thermodynamic parameters.
- Load prediction
- Firing order optimization
- Crankshaft torsional vibration analysis
- Crankshaft stress analysis
- Cranktrain balancing
- Connecting rod analysis
Valvetrain analysis
Virtual Engine provides a high degree of freedom in modeling and simulation. The Valve Lift Designer allows design and optimization of lift curves with respect to velocity, acceleration, and jerk. All Valvetrain types including CVVL can be analyzed kinematically or dynamically. Valvetrain models are created in a unique two-step process from ‘single’ to ‘complete’ valvetrains with flexible components if desired. Virtual Engine’s unique communicator technology allows complete valvetrains to be built on the fly by assembling multiple single valvetrains via a camshaft.
- Cam profile design
- Optimum layout for best gas exchange
- Maximum possible speed and seating velocity
- Dynamic valve spring behavior
- Friction prediction
- Contact forces and hertzian pressures
- Cam driving torques
Piston and ringpack analysis
Virtual Engine has advanced 3D simulation features to predict dynamics of the piston ring pack, piston, piston pin, and connecting rod assembly. It allows analysis of the piston secondary dynamics, the impact of the crankshaft and/or piston pin offset on friction and resulting NVH through piston slap. Boundary lubrication and asperity contact are calculated based on the Greenwood and Trip method. The 2D hydrodynamic approach uses a simplified version of the Reynolds equation, thus providing fast solutions. The comprehensive full 3D elastohydrodynamic solution addresses the high-fidelity piston assembly simulation needs.
- Piston slap and NVH analysis
- Friction and wear prediction
- Skirt profile and pin offset optimization
- Ring pack optimization
Timing and accessory drive
Virtual Engine allows the building of complete, multi-staged timing and accessory drives, comprised of mixed chain and belt drive stages. Building blocks are provided for the Chain/Belt Drive analysis: chain types including bushing, roller, silent/inverted tooth, sprockets including circular or non-circular using external CAD geometry, involute sprockets for silent/inverted tooth chain, fixed, translational, pivot and flexible chain guides, hydraulic tensioner, toothed belts, ribbed belt such as Poly-V belt, circular and elliptic idler/pulley, and tensioner. Even complex belt and chain drive templates can be easily created with the Chain/Belt Template Wizard.
- Timing and accessory drive design
- Chain/belt dynamics
- Belt life prediction
- BSG start-stop systems
- Drive layout
- Tensioner system analysis
Geartrain and driveline
Virtual Engine provides a complete tool set to build any type of geartrains, analyze them using either 2D or 3D advanced gear EHD contacts, and assemble them with other subsystems. Gears may be used to build gearboxes or transmissions, but can also be part of multi-staged timing or accessory drives. External or internal, spur, helical, scissors, and planetary gear sets can be modeled using rigid or flexible modeling elements.
- Transmission error and resulting speed irregularities
- Gear whine and rattle
- Backlash studies
- Tooth loads
Bearing analysis
Virtual Engine provides journal and roller element bearings in different fidelity levels. Available bearing types include linear, non-linear, mobility, hydrodynamic, elastohydrodynamic (EHD), and thermoelastohydrodynamic (TEHD) models. Advanced bearing model types are based on the Patir and Cheng average flow model where flow factors can be calculated if a measured surface profile is available.Asperity contact calculation has two options, one being the Greenwood & Tripp model. An additional option is provided based on a measured surface profile.
- Minimum oil film thickness
- Maximum oil and contact pressure
- Displacements
- Friction prediction
- Wear prediction
