PID Controller Exercise 6— Performing the Simulation
Simulation residuals (PID Controller)
1. In the Flow Analysis Tree, under Physics select Common.
2. In the Properties panel, Model tab, set values for the options as listed below:
◦ Number of Iterations—100
◦ Time Definition—Steady State Simulation
◦ Result Saving Frequency—100
3. In the Run group, click 
Run to begin the simulation. The default settings are set to Start from Initial Values and Steady in the Run group
Run to begin the simulation. The default settings are set to Start from Initial Values and Steady in the Run group4. Click 
XYPlot Panel to view the residuals for the steady simulation.

 | The default convergence criterion is 0.001 for steady state simulations. The simulation is completed, when the residuals for all the variables drop by 3 orders, or the maximum Number of Iterations is reached. |
