[BUG]Net node works abnormally when

[XLin0mu]

Minimum test case:

using ACME

c_work = @circuit begin
    src = voltagesource(), [+] == gnd_up, [-] == gnd_down
    r1 = resistor(10), [1] == gnd_up, [2] == gnd_down
    G = voltageprobe(), [+] == gnd_up, [-] == gnd_down
end;

c_not_work = @circuit begin
	src = voltagesource(), [+] == gnd_up, [-] == gnd_down
    r1 = resistor(10), [1] == gnd_up, [2] == gnd_down
    G = voltageprobe()
    G[+] == gnd_up
    G[-] == gnd_dowd
end;

model_work = DiscreteModel(c_work, 1/50);
model_not_work = DiscreteModel(c_not_work, 1/50);

y_w = run!(model_work, 16sin.(2π*1000/44100*(0:99)'))
y_n_w = run!(model_not_work, 16sin.(2π*1000/44100*(0:99)'))

G[-] == gnd_dowd

Typo? If you use gnd_down here, y_w and y_n_w become the same, which I suppose you were expecting?

The code as provided gives

Warning: Model output depends on indeterminate quantity

which is correct, as gnd_dowd is floating and the voltage is therefore indeterminate.

Closing as from my perspective, this works as it should, but please comment if I misunderstood.
