This is where the model comes to life. A WAVE model is a network of two primary elements:
Tutorial Exercise: To build a simple intake system, start by placing an Ambient Junction (Atmosphere). Draw a Duct from it connecting to an Orifice Junction (representing the throttle body). Connect another Duct from the Orifice to a Volume Junction (representing the intake plenum).
Objective: Simulate 1500 RPM, wide-open throttle, gasoline combustion. ricardo wave tutorial

Expected Outputs from Tutorial:
Component List: 1. SB1 (intake) – 1 atm, 300 K 2. Duct1 – L=200 mm, D=40 mm 3. Junction1 – 3-way 4. Duct2 (runner) – L=150 mm, D=35 mm 5. IntakeValve – lift profile (sine), max 8 mm, IVO 10° BTDC, IVC 40° ABDC 6. Cylinder – bore=80 mm, stroke=90 mm, CR=10:1 7. ExhaustValve – EVO 50° BBDC, EVC 10° ATDC 8. Duct3 (exh) – L=250 mm, D=35 mm 9. SB2 (exhaust) – 1 atm, 300 K
Fuel: gasoline, stoichiometric (λ=1) Speed: 3000 RPM Combustion: Wiebe (start 10° BTDC, dur 60°, shape 2)
After running → WAVE computes torque, airflow, and knock index.
After simulation, WavePost automatically opens. If it doesn't, click the "Results" button. This is where the model comes to life
