Before running any simulation, you must set the global operating conditions.
What is the specific you are modeling? (e.g., 4-cylinder gasoline, V6 diesel, hydrogen engine)
Define the : Choose the working fluid model. For standard applications, select Air / Combustion Gas Product . For advanced simulations (e.g., E-fuels or Hydrogen), ensure the correct chemical properties or custom fuels are appended. Step 2: Defining the Fuel
Before you can apply UPD, you must construct a correct baseline model of your engine. avl boost tutorial upd
: A frequency domain solver predicts the acoustic performance of engine components. External Links : Connects with for 3D CFD simulations and AVL CRUISE for full vehicle powertrain analysis. Tutorial & Workflow Overview
Once calibrated, you can run parametric sweeps to optimize performance. Setting Up a Case Matrix
If an update is available, click "Download." This allows you to install the update while keeping your previous installation intact if desired. Step 4: Installation Run the downloaded installer. Follow the on-screen prompts. Before running any simulation, you must set the
): Check for pumping losses (the lower loop of the 4-stroke cycle). An expanded pumping loop indicates restrictive intake/exhaust geometries or poor valve timing.
Valve timing and lift profiles are critical for accurate gas exchange. Import or manually define intake valve opening (IVO), intake valve closing (IVC), exhaust valve opening (EVO), and exhaust valve closing (EVC) points, as well as the lift curves in millimeters versus crank angle. You can use classical spline approximation methods to generate smooth cam profiles.
: For complex hardware-in-the-loop applications, BOOST models can be integrated into environments like NI VeriStand 4. Post-Processing and Results Analysis After the status bar indicates completion, use the Results Tab to visualize data. Data Viewer For standard applications, select Air / Combustion Gas
Enter bore, stroke, compression ratio, and connecting rod length.
