Please, make the needed corrections and restart the compilation.

Compilation process interrupted.

Hello!

When core couplings divide the circuit, there should be no nodes in separate electrical circuits that are connected directly. Even though it seems that there are no nodes connected directly in your circuit, ground components are connected to the same node.

There are two ways to fix this issue, which are thoroughly explained in this FAQ: How to connect grounds in multi-core models?

For your particular case, you can either select the checkbox Set Ground component scope to core, in Circuit Solver settings of Model settings, or you can increase the number of phases in core coupling and then connect the ground nodes to an additional port of the core coupling.
