Error: "Each physical network must be connected to exactly one Solver Configuration block. There is no Solver Configuration block connected to Physical Network with the following blocks..."

I would like to Implement the following (see image on the left) Pulse Width Modulation (PWM) circuit on Simulink (see image on the right). However, i keep getting the following error:

"Each physical network must be connected to exactly one Solver Configuration block. There is no Solver Configuration block connected to Physical Network with the following blocks..."

Could someone help me out? Thanks!

Dear,

You have to recuired Solver Configuration block at grounding point as shown in attached file

the Solver Configuration Block can be obtained from

Simulink Library> simscape>foundation library> utilies

Hello Pemendra,

to clarify, the simscape configuration block does not need to be connected at the grounding point. It can be connected anywhere. Many people connect it to a ground, but this it does not need to be.

Joel

Thankyou very much Joel,

For clarification

Hello,

the solver configuration block is a simscape block under utilities that you can connect to any part of your simscape network. It associates local solver settings for that simscape network since simscape uses more complex solver's than simulink does. You should be able to start with the default settings.
