How to drive the thyristor?

I want to simulate a bridge rectifier, and to control its firing angle. but it has error, such as 'ERROR(ORPSIM-15142): Node GND is floating'. How should i do?

how should i insulate the ground of driver and main circuit? And in many simulation, I don't known how to insulate different ground,such as transformer or the driver of semiconductor device.

Another question is, why can't I uploade the picture?

Thank you very much!

There is no DC path between the circuit node named GND and the 0 reference node. If you want them to be isolated, use a 1G resistor, for example, to provide a DC path for isolated circuits to the 0 reference node.
