Each physical network must be coHow to clear this error on simulink. (There is no Solver Configuration block connected to Physical Network with the following blocks)

I'm trying to model a Ward Leonard system on MATLAB simulink, where an AC motor drives the DC generator which in turn drives the DC motor as a method of speed control back in the days, but i'm having this error (check the screenshot) popping up, how do I find a solution to this?

It looks to me as if the Gain block is a basic Simulink block. Basic Simulink blocks are in a different "domain" than Specialized Power System blocks, so possibly you also need to connect a basic solver block.

Each physical network represented by a connected Simscape™ block diagram requires solver settings information for simulation. The Solver Configuration block specifies the solver parameters that your model needs before you can begin simulation.

Each topologically distinct Simscape block diagram requires exactly one Solver Configuration block to be connected to it.

The diagram "looks" like it is one continuous topologically distinct block.

However, the existance of the green line shows that there is at least one connection in a different solver domain.
