Solving Electrochemical Models
Due to the highly nonlinear nature of electrode kinetics, some electrochemical models can be difficult to solve. This section includes some general tips and tricks to facilitate model solving, troubleshooting, and ways to improve solution accuracy.
Usually, convergence issues occur due to, and are resolved by correcting, settings in the physics (inconsistent parameter values, missing initial values, lacking boundary conditions etc), rather than actual solver settings.
