可以找到很多与腐蚀或电镀相关的，使用三次电流分布的案例，如：//www.denkrieger.com/model/copper-deposition-in-a-trench-2112

请问直接使用三次电流分布有相关案例视频吗，手动耦合经常报错

二次电流分布+稀物质传递等价于“支持电解质-三次电流分布”，从方程形式上两者完全相同，不过前者需要手动做耦合，后者耦合已经自动完成。适用于，电解液电导率对离子浓度变化不敏感的场景，比如加入了大量支持电解质。如果电解质电导率与离子浓度有关，建议采用“电中性-三次电流分布”，它默认考虑电解质离子电导率与浓度有关，确切将与离子通量有关。

The electrode potential is the difference in potential between the solid-liquid interface, and it is not directly defined in COMSOL. Generally, only the solid-phase potential is defined, while the liquid-phase potential and lectrode potential are calculated based on interface dynamics and solution properties.

In general, the definition of electrode potential in textbooks or literature is more complex, but it is emphasized that the electrode potential is not equal to the potential difference between the electrode and the solution. However, I found that COMSOL’s definition of electrode potential is this. Does this definition cause the simulation results to be inconsistent with the objective physical facts? Thank you!
