Open existing Simulink model from Matlab, domain error!

i need to open an existing simulink model from my Matlab GUI. I am not into Simulink at all and i just have to make it work somehow. To open the model i use the command

    open_system('filepath_to_model')

Now an error occurs:

    Warning: Physical modeling domain definition file psatdomain.m not found. You will not be able simulate this model. Please close
    your model, then add the domain definition file to the MATLAB path and re-open your model.

What does this error mean? i added psatdomain.m to the directory of the model but the error remains the same.

% PSATDOMAIN defines the domain for the PSAT-Simulink library

I would be glad for your help so that i can open an existing Simulink model and run it from my Matlab GUI.

Thank you very much!!

Best regards, John

"Physical modeling domain definition file" is from SimScape

It finally worked. I guess it was a kind of path issue. I had to add the path to the respective folder for the executed functions and then it worked.

Warning: Physical modeling domain definition file p1.m not found. You will not be able simulate this

model. Please close your model, then add the domain definition file to the MATLAB path and re-open your

model.

How can i solve this?

Hello Prabesh,

Did you find the solution to your problem, as I am also facing the same problem.

Warm Regards

You need to locate a copy of the domain definition .m file and make sure it is on your MATLAB path.

Also, when you get this error, you have Simscape elements in the model and will need Simscape to simulate the model. I am not sure what would happen if you tried to open such a model when you did not have Simscape installed, but not having Simscape installed increases the risk that you will not have the domain .m files installed.
