How to stop the solver based on the static pressure difference between two monitors setup upstream and downstream?

 

[cbhavsar]

The easiest approach to monitoring pressure difference is to set the outlet relative pressure to zero. Monitoring a pressure in the model is then monitoring the pressure difference with the outlet. To stop the solver based on monitor, you can use Monitors --> Convergence Monitors --> Convergence Manager. The convergence manager facility allows you to set convergence conditions on the solution that are based on the values from surface, volume, lift, drag or moment monitors. Convergence check for the monitors is independent of that for the equation residuals. By default, the solution convergence will happen if either monitor convergence criteria or residuals convergence criteria is satisfied. If you want to rely only on the monitor values to decide convergence, clear the Check Convergence check boxes in the Residual Monitors dialog box. You can also see Solution # 2042636 for similar details.
