Dear COMSOL Community
I have a question regarding the example of the Vanadium Redox Flow Battery (www.comsol.com/showroom/documentation/model/14153/).
I have tried to simulate it but I get following error message:
Undefined value found.
- Detail: Undefined value found in the equation residual vector.
