[Archive] Varying voltage on spacecraft surface

Message by Alexandru Cornogolub:
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?

Message by S├ębastien Hess:
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.
