    Hello,

    Can you post the circuit?
    Can you also describe what goes wrong.

    Many simulators object to " floating" nodes, with no DC path to ground. One or more floating nodes could easily result if you are modelling a capacitive divider.

    A common solution is to add extremely large value resistances (say 10^30 ohms, depending what values the software will support) so as to define the DC potentials at the nodes concerned.
