Step 3: The Combustion Model

For the cylinder element, you have three main options for defining combustion:

1. Wiebe Function: Best for baseline calibration.
2. Vibe (Double Wiebe): Better for knock prediction.
3. Predictive Combustion Models (Updated): The updated Cylinder models now include enhanced predictive combustion templates specifically tuned for pre-chamber spark ignition (PCSI) and high tumble flow concepts.

Strengths (What Works)

1. Relevant Keywords

   • “AVL BOOST” correctly targets the engine simulation software.
   • “Tutorial” suggests a learning resource.
   • “Upd” (likely “update”) hints at either an updated tutorial or software version.

2. Target Audience

   • Appeals to beginners or intermediate users looking for current guidance.

Key changes from older tutorials:

• Time steps: Use “Automatic CFL-based” (CFL = 0.8). Do not manually enter 1° crank angle steps – the solver optimizes it.
• Cycle convergence: Set to 20 consecutive cycles (new default is 10; increase for turbo engines).
• Initial conditions: Enable “Initialize from previous cycle” (saves 30% runtime).
