From the Palette:
You have built geometry. Now you need to "start" the engine.
After completing the basic tutorial, users typically explore: ricardo wave tutorial
| Error | Likely Cause | Fix | |-------|--------------|-----| | Simulation won’t start | Missing boundary condition | Add SB or set initial pressure | | Negative pressure during intake | Too small intake duct diameter | Increase diameter or check valve Cd | | No combustion | Wrong Wiebe start angle | Set start before TDC | | Non-converging cycle | Wrong initial condition | Start from IVC using motored pressure |
Your schematic should now look like a straight line: Air In -> Intake -> Cylinder -> Exhaust -> Air Out. From the Palette: You have built geometry
Before drawing pipes, you must tell the software what is flowing through them.
Open Ricardo Wave. You will be greeted by the WaveBuild GUI. This is a schematic canvas. Here is your road map: Initial Conditions: Set initial pressure in all ducts
If you are modeling a full engine, you would use the Engine template, which allows you to define cylinders, pistons, and valve lift curves.
However, for a simpler acoustics tutorial (like an exhaust muffler), you typically use a Flow Source or Speed Source. This artificially generates the pressure pulses that mimic an engine firing order, allowing you to test how your muffler attenuates sound without simulating combustion.
