Is the current (I) in charge solver results window a total current?

      Hello,

      I have a concern regarding the current (I) present in the charge solver results window (see figure) , in the cathode results specifically. I am simulating a PIN photodiode. So this current (I) is the current at the cathode only? Or of the whole structure? If it is a current in cathode only, then how can I calculate the total current in the whole PIN structure (anode+cathode+ intrensic junction layer) ?

      Remark : at the anode there is a current result (I) also in the results window.

      As you mentioned, both cathode and anode have the total current. Ideally they are the same. However due to some reasons, such as meshing ect., they have some difference. If the difference is large, you will need to adjust the settings to see if they converge.
