[Archive] Varying voltage on spacecraft surface

Message by Alexandru Cornogolub:
Hello,
I have simulated a simple case where the surface of the spacecraft is maintained at constant voltage, however I see during the simulation that the voltage varies anyway. Does someone know what is the problem?

Hello,
how did you force the constant voltage? SPIS always computes the currents on the surfaces to update the surface potentials, except if you force it to not do it.
