Further Simulations
If you want to experiment with the model by changing parameter values and simulate new polarization plots, you have to disable the Transport of Diluted Species interface in the stationary study as follows:
1
In the Model Builder window under Study 1
click Step 1: Stationary
.
2
Disable the Transport of Diluted Species interface in the table shown in the Physics and Variables Selection section by clearing the checkbox in the ‘Solve for’ column.
click Step 1: Stationary 
.
