Ricardo WAVE is a premier 1D gas dynamics simulation tool used globally by engineers to optimize engine performance, emissions, and fuel economy. This tutorial provides a comprehensive walkthrough for building and running your first engine simulation. 1. Getting Started with the Interface The primary environment for building models is WaveBuild.
Model Canvas: The central workspace where you drag and drop engine components. Elements Library: Contains all building blocks, including:
Flow Elements: Ambients, cylinders, ducts, injectors, and throttles. Mechanical Elements: Turbo shafts and engine blocks. Control Elements: Sensors and actuators for advanced logic.
Session Tree: A hierarchical list of all components currently in your model.
Object Properties Panel: Located on the right, this is where you input specific data like bore, stroke, and duct length. 2. Building a Single-Cylinder Model
To create a basic Spark Ignition (SI) or Diesel model, follow these six core steps:
Initialize the Model: Open WaveBuild and set your general parameters, such as the unit system (typically SI) and simulation duration (e.g., 30 cycles).
Layout the Flow Network: Place junctions (ambients) and connect them with ducts to represent the intake and exhaust manifolds.
Define Ambient Conditions: Set initial pressures (default 1 bar) and temperatures (default 300 K) for the intake and exhaust boundaries.
Configure Cylinder Geometry: Enter the bore, stroke, and clearance height. You can use variables for parameters like the compression ratio to allow for easier optimization later.
Set Up Valves: When a duct connects to a cylinder, a valve object is automatically created. You must define the lift profile and flow coefficients for both intake and exhaust valves.
Add Fuel Injection: Place an injector and specify the fuel-air ratio or mass flow rate. For diesel engines, you will often use the "diesel web" combustion model and define start-of-injection timing. 3. Advanced Simulation Techniques Once you have a basic model, you can expand its complexity:
Turbocharging: Add compressor and turbine blocks connected by a turbo shaft. You must input compressor and turbine performance maps (found in the TC map folder) to simulate boost.
Heat Transfer: Use the Woschni correlation (the default model) to simulate thermal distribution across the cylinder head, piston, and liner.
Design of Experiments (DoE): Use the optimization tool to automatically run dozens of simulations. By varying parameters like valve timing or compression ratio, you can find the ideal configuration for maximum torque or minimum fuel consumption. 4. Running and Analyzing Results
After building the model, initiate the solver. Once the simulation completes, use WAVE Post to view your results. Key outputs to review include:
Brake Power and Torque: Performance indicators across the RPM range.
Brake Specific Fuel Consumption (BSFC): Efficiency of fuel usage. Volumetric Efficiency: How well the engine "breathes".

Ricardo WAVE (now part of Realis Simulation) is a premier 1D gas dynamics and thermodynamics simulation tool used globally by automotive engineers to optimize engine performance. This tutorial provides a comprehensive guide for beginners to navigate the interface and build a foundational engine model. Introduction to the Ricardo WAVE Interface
Before building a model, it is essential to understand the primary workspaces within the WaveBuild GUI:
Model Canvas: The central area where you drag, drop, and connect engine components.
Elements Library (Session Tree): A categorized list of components, including flow elements (cylinders, ducts, injectors), mechanical elements (turbo shafts), and control blocks.
Object Properties Panel: Located on the right, this is where you input specific physical characteristics like bore, stroke, and clearance height.
Output Tab: Displays system messages and errors during a simulation run. Step-by-Step: Building a Single-Cylinder SI Engine Model ricardo wave tutorial
Follow these six primary steps to create a basic spark-ignition (SI) gasoline engine model: 1. Setting General Parameters
Initialize your simulation by defining global settings in the Simulation Control panel: Units: Select SI [mm] as the base unit system.
Simulation Duration: A typical setting for a gasoline engine is 30 cycles.
Fuel Properties: Open the Fuel Property Tag Selector and select a standard fuel like INDOLENE. 2. Building the Flow Network
Construct the physical layout on the canvas by dragging elements from the tree:
Place two Ambient junctions (one for intake, one for exhaust). Add an Engine Cylinder element in the center.
Connect these using Ducts and Orifices. In WAVE, drawing a line from an Ambient to an Orifice creates a duct automatically. 3. Defining Component Geometry Double-click each element to enter its physical dimensions:
Ambients: Keep default values (1.0 bar, 300 K) for standard atmospheric conditions.
Ducts: Enter the measured length and diameter. Set Discretization Length (e.g., 35 mm) to determine how the solver divides the duct for calculations.
Cylinder: Input the Bore (e.g., 78.1 mm) and Stroke (e.g., 82.0 mm). 4. Configuring Engine Operating Parameters
Access the Engine General panel to define how the engine runs:
Operating Parameters: Set the Engine Speed. You can use a constant like SPEED and define it in the Constants Panel (e.g., 6000 rpm).
Combustion Model: Choose a submodel like the Wiebe combustion model for SI engines or a diesel-specific model for compression ignition. 5. Defining Valves and Fuel Injection
Valves: Use the Valve List panel to add intake and exhaust valves. You must define a Lift Profile (often by selecting a pre-saved .prof file) and set the Cycle Anchor to time the valve opening.
Injectors: Drag a Proportional Fuel Injector onto the intake duct. Define the Air-Fuel Ratio (e.g., 14.7 for stoichiometric) in the properties. 6. Running the Simulation and Analyzing Results
Input Check: Click the Run Input Check button to verify there are no errors in your setup.
Execution: Start the simulation. The solver will process the thermodynamic cycles until convergence.
WAVE Post: View results in the post-processing tool. Here, you can generate graphs for Brake Torque, Volumetric Efficiency, and Brake Specific Fuel Consumption (BSFC). Advanced Functionality
Once comfortable with basic models, you can explore advanced features:
Part 1: The Call of the Concrete
Leo was a man who lived in two dimensions. He existed perfectly on the X-axis (work) and the Y-axis (sleep). The Z-axis—depth, flair, sazón—was a terrifying void. He watched people at parties lean against walls with effortless cool, their hands doing things his own hands seemed allergic to. He couldn’t even nod to a beat without looking like a broken metronome.
Then, he saw the video.
A man, known only as "Ricardo," walked across a sun-drenched piazza. He wasn't just walking. He was narrating his own existence with his shoulders. He performed a gesture—a smooth, circular wave that started at his chest, rolled through his arm, and ended with a finger-gun and a wink. It was absurd. It was majestic. It was the Ricardo Wave.
Leo became obsessed. This wasn't a dance move; it was a philosophy. A statement that said, "I am here, I am in motion, and I am utterly unbothered."
He cleared the living room furniture, pulled up the video, and began.
Part 2: The Three Swells (The Tutorial)
The video’s host, a calm woman named Maya, appeared on screen. "Forget the man," she said. "Become the wave."
She broke it into three "Swells."
Swell One: The Anchor (The Chest Pop & The Roll)
"Most people fail because they start in their fingers," Maya explained. "No. The wave lives in the core."
Leo planted his feet shoulder-width apart. He felt foolish.
"Step one," Maya instructed. "Push your right chest forward, as if you're about to bump a ghost with your pec. At the exact same time, pull your right shoulder back."
Leo tried. He just looked like he was having a spasm.
"Slower," she cooed. "Feel the tension ribbon from your sternum, over your collarbone, to the top of your shoulder. This is the source. The chest initiates. The shoulder receives. Practice this until you can do it while holding a full cup of coffee. No spills."
Leo practiced for an hour. His cat, Socks, watched with judicial disappointment. But then, finally, click. He felt the isolated roll—a smooth, vertical loop-de-loop from his breastbone to his deltoid. He grinned. Ricardo WAVE is a premier 1D gas dynamics
Swell Two: The Traveler (Elbow Leads, Wrist Obeys)
"Now," Maya said, "send the wave down the arm."
The most common mistake? Moving the hand first. Ricardo never chases. Ricardo commands.
Maya demonstrated in slow motion. As the shoulder reached its apex, she let her elbow lift outward, as if pointing to a friend across the room. The elbow was the engine. "Don't think about your hand yet," she said. "Let the elbow pull the forearm into the air."
Leo watched his own arm. His elbow lifted. His forearm, like a flag in a gentle wind, followed two seconds behind. It was floppy. Uncontrolled.
"Relax the wrist," Maya said. "A dead fish flops. A wave flows. Your wrist is water."
He relaxed. Suddenly, the movement became fluid. The energy from his chest moved to his shoulder, his shoulder pushed the elbow, and the elbow threw the hand out in a lazy, powerful arc. It wasn't a wave. It was a transfer of power.
Swell Three: The Resolution (The Finger-Gun & The Bounce)
"Now, the signature. The punctuation."
As the hand reached the end of its journey—fingers pointed forward, palm down—Maya snapped her hand into a soft, playful finger-gun. Pew.
But it wasn't just the hand. At the exact moment the finger pointed, she bounced lightly on the ball of her back foot. A tiny, rhythmic hop.
"The bounce is not a dance step," she explained. "It's a laugh. It's saying, 'I know I look ridiculous, and that's why it's cool.' The finger-gun is aimed not at someone else, but at your own reflection. The Wave is a salute to your own audacity."
Leo tried the full sequence. Chest roll. Shoulder. Elbow pull. Wrist flop. Finger-gun. Hop.
He stumbled. The hop was off-beat. The finger-gun was aggressive, like he was trying to start a moped.
He practiced for three more days. He did it while brushing his teeth. While waiting for the microwave. While walking to the mailbox.
Part 3: The Piazzetta
One week later, Leo found himself at a work party. It was loud, crowded, and he was once again a statue against the wall. The company DJ played a terrible remix of a song he almost liked.
Then, someone bumped into him. He looked up. It was the new graphic designer, a woman named Elena. "Sorry!" she shouted over the music. "You look like you're about to dissolve."
Leo felt the heat rise to his cheeks. But then he felt it—a phantom tickle in his sternum. The memory of the Three Swells. The cat’s disappointment. Maya’s voice: The bounce is a laugh.
He looked at Elena. He looked at the dance floor.
He didn't think.
His chest pushed forward. The roll moved to his shoulder. His elbow lifted—slow, confident. The hand followed like a lover’s sigh. And as his fingers curled into a loose, playful gun, he bounced on his back foot and pointed directly at Elena’s shoulder.
Pew.
He didn't say a word. He just did the Ricardo Wave.
Elena’s eyes widened. Then, she laughed—a real, surprised laugh. And without missing a beat, she performed a crisp, ironic bow, as if accepting a ridiculous crown.
He didn't become Ricardo overnight. But for the first time, Leo wasn't a ghost in the machine. He was a wave in the ocean—temporary, silly, and perfectly in motion. He had learned the move.
But more importantly, he had learned that the confidence wasn't the reward for doing the Wave correctly.
The confidence was the Wave.
Since "The Ricardo" is widely known as a viral dance move (often associated with the meme of Ricardo Milos) or as a variation of arm waves in popping, this guide focuses on the Arm Wave technique, which is the foundational skill required to perform "The Ricardo" smoothly.
Ricardo Wave is a complex tool, but once you master the flow network logic, you can design intake systems that use sonic waves to force-feed your engine better than any supercharger.
Now, go simulate. Good luck.

Ricardo WAVE is a powerful 1D-CFD engine simulation tool used for performance, acoustics, and thermal analysis. To help you get started or refine your workflow, here are the most helpful features and setup steps based on common tutorial structures. 1. Key Simulation Features
Design of Experiments (DoE): Automates the optimization of engine parameters (like duct lengths) by running multiple combinations of variables within defined minimum and maximum ranges.
Woschni Heat Transfer: A built-in correlation used to calculate surface temperatures and heat rejection to coolant/oil, essential for predicting wall temperatures where physical sensors cannot reach. Step 1: Building the Model (WaveBuild)
Constants Table: Allows you to define variables (e.g., SPEED) that can be changed across different "Cases" without rebuilding the model geometry.
Excel Integration: You can set up your Constants Table in Excel and save it as a .txt (tab-delimited) file to perform interpolations and avoid the "tedious interface" for large datasets like cam specs or flow coefficients [FSAE Forum]. 2. Core Workflow for a Single Cylinder Model
The standard tutorial path for building an SI (Spark Ignition) engine model typically follows these phases: Key Tool/Panel 1 General Setup
Set units to SI [mm], select fuel (e.g., INDOLENE), and define simulation duration in cycles. 2 Flow Network
Drag Ambient, Orifice, and Cylinder elements onto the canvas and connect them with Ducts. 3 Element Geometry
Input duct lengths, diameters, and Discretization Length (standard is ~35mm). 4 Engine Parameters
Set bore, stroke, and connecting rod length in the Engine General Panel. 5 Valves & Injectors
Add intake/exhaust valves with Lift Profiles and a proportional fuel injector. 6 Run & Post-Process
Perform an Input Check, run the solver, and use WavePost to view pressure/temperature time plots. 3. Useful Troubleshooting & Tips
Convergence Check: Always check the R-squared value and RMS errors in the experiment analysis panel; values closer to 1 indicate high confidence in the data fit.
Duct Coloring: In WaveBuild, yellow ducts indicate missing geometric data; they turn black once diameters are properly defined.
Case Manager: Use the Case Manager at the bottom of the canvas to navigate between different simulation scenarios (e.g., different RPMs). Remember: red background in the case field means you are NOT in Case 1 and should not change geometry. To help you further, could you tell me:
What type of engine are you modeling (e.g., single-cylinder, multi-cylinder turbo, Diesel)?
Are you looking to optimize a specific performance metric (like torque or fuel consumption)? Which version of Ricardo WAVE are you using?
