: Use Plenum (PL) elements to model volume changes like intake manifolds. 2. Cylinder & Combustion Setup Geometry : Enter bore, stroke, and connecting rod length. Combustion : Vibe Function : Most common for predictive heat release. Direct Input : Use measured heat release data if available.

| Symptom | Possible Cause | Fix | |---------|----------------|-----| | Simulation fails at 0° CA | Invalid lift curve (negative or zero maximum lift) | Check lift data; use 1 mm as min lift | | Pressure spikes at valve overlap | Incorrect valve timing | Ensure EVO > IVO on same cylinder | | No torque at low rpm | Combustion too late (SOC > 10° ATDC) | Advance Vibe start angle to -5° | | Convergence warning after 20 cycles | Wrong initial pressure/temperature | Initialize from previous converged cycle | avl boost tutorial upd
