Dear Simon,

not exactly, since you either integrate the whole SC circuit or nothing. There is however a only way around (which I already used), which is to play on the values of the capacitances, having one/some of them big compared to others (these capacitors won't charge).

For example you define the fixed potential surface as SC ground and define a large SC capacitance (big enough but not more, the solver coulsd experience accuracy issues otherwise) pluged from infinity to SC ground only (hence negative value, cf doc). Then plug a regular (small) capacitance between your SC ground and other surfaces.

Is it possible to have a self-consistent simulation where charge integration is taking place but to hold one particular surface/group at a fixed potential and let the other surfaces charge?
