I am using "Potential". I got a warning and the simulation diverged:

My model has two electrochemical reactions for electrodes.
I set a certain potential value for each electrode.
I noticed UDSs were automatically loaded, so I disabled them since I did not use UDFs.
Someone said It's hard to converge due to the numerical instability in the range of low concentrations.
Do I have to use UDFs for electrochemical reactions, or is there a way to converge?


Thank you for your help!
