electrical potentials

Hi,
I´m analyzing the distribution of electrical potentials through different geometries with varying conductivities. An active electrode is firing with 1V under quasi-static conditions. To analyse the behaviour I modeled a big sphere which also contains the ground electrode and encloses the 'structure of interest'.
Now I want to manually define that the electrical potential on the big sphere should be 0, or how can I define Ve in a certain distance??
Hope someone can help!
Best, Manfred

Manfred,
you can apply a ground or electric potential BC to the sphere. It is unclear what you mean with 'Ve in a certain distance'?
Cheers

Thanks a lot Edgar,
I simply applied the ground potential on the spheric wall. However, a new question came up:
I changed the sphere to a cuboid setting it as ground. Is it possible in COMSOL to virtually prolong one side surface to infinite setting the potential to 0?
Cheers, Manfred
