Simulation

This section explains the settings to start/ run the simulation.

1. Click on Simulation Panel.
2. Select By Time Steps under Time Definition.
3. Define Simulation Time (Duration), Number of Time Steps, Number of Iterations, and Result Saving Frequency as 10 s, 2000, 5, and 200 respectively (see, Figure 8.69).
4. After you save the project, click Start to run the simulation.

5. The result files are saved as .sres in the working folder (Example: selfpropelledboat_model_0600.sres). The number of result files depends on the Result Saving Frequency.

Note: The Result Saving Frequency option in the Simulation Panel is set to a small value (say 5 or 10) before running the simulation to obtain better animations.

Note: The default Converge Criterion is 0.1 for Transient simulations. When the residuals for all the variables drop by one order or the maximum Number of Iterations is reached, the calculation proceeds to the next time-step.
