In DC steady-state analysis PSpice treats all capacitors as a open circuit and inductors as a short circuit. And this is why the nodal voltage is floating.

How to resolve this problem so I could simulate AC sweep with no errors !

Add 1G resistor parallel with capacitors.

Or skip DC point calculation.
Also, why the hell is this a poll?

Skipping does not help!

There is no errors , but ""print parts"" shows that voltages and currents are zeroes!

Thanks for help!
If i can ask one more question ?
Im makilng parallel L circuit with coupling !
And there is this error!

Try show as the circuit diagram.
