Purpose

Set the stopping limit and, for transient simulations, the physical time controls.

Steps

1. Select Steady or Transient first.

   

2. For Steady, enter the total iteration limit.
3. For Transient, enter total time, time step, and iterations per time step. Review the enabled controls after changing physical models.

Inputs and units

Input or value	Meaning	Units
Iterations	Steady iteration limit or iterations per transient time step, according to mode.	Integer count
Total time	Requested transient simulation duration.	s
Time step	Requested time increment for transient integration.	s

Limitations

• Reaching an iteration or time limit does not prove convergence. High-speed and mixture cases use model-specific time controls; check their enabled fields after changing models.
