How to Use the Calculator
The Courant number is a dimensionless quantity that measures the relationship between the time step size, flow velocity, and grid size in a simulation. It plays a vital role in maintaining numerical stability, particularly in explicit solvers. A Courant number less than or equal to 1 is typically recommended for stability.
This calculator simplifies the process of computing the Courant number by automating the formula. It helps you:
- Validate your simulation settings.
- Identify if the chosen time step and grid size are appropriate.
- Avoid simulation instability and errors.
- Enter Flow Velocity: Input the velocity of the fluid in meters per second (m/s).
- Input Cell Size: Specify the size of the grid cell in meters (m).
- Set the Time Step: Provide the time step in seconds (s).
- Click "Calculate": Press the yellow button to compute the Courant number.
- Get Results: The Courant number and a fun fact about CFD will be displayed instantly.
