when i tried to run a file developed using simulink/ simscape that error was shown

pgm description:

had a voltage supply, dc motor, incremental shaft encoder voltage sensor, ps-s converter, scope.

when i run the file it shown the following error:

"""Simscape components in untitled are not connected to a Solver Block."""

additionally connected a solver.

when i run the following error was shown:

"""Number of variables exceeds number of equations. Check for missing reference node."""

i donno what to do. is there any settings to be done in the blocks to do?

I think you need to insert a Ground block also.

Sorry, I don't have any experience with SimScape. My suggestion was only from other answers I've seen on this forum. Perhaps you could look at some of the demo models from the documentation to see how the Ground block is used?
