Boundary Current Source and Sink

Hi everyone,

I have a simple pair of electrodes, one with a current excitation of 1mA and a counter electrode with a current excitation -1mA, which is meant to be the "Boundary current sink" for the "boundary current source".

However, my computations won´t stop and simply run forever, so I´m not able to retrieve any results, from my simulation.

My question is, wether it is the right approach for this kind of setup, to use the Boundary Current Source feature for a source and a sink?

Thanks for the help Best regards

Jonas
