SimulationInput cannot find my model

Hello,

I need a quick help to understand why my code is not able to call for the model. My project folder has to internal folder, one called "SCRIPT" and the other called "MODEL" where the main simulation model resides (.slx). When I use the command:

in(i) = Simulink.SimulationInput('C:/ggit/test/Project/MODEL/PhC200.slx');

I get the following error:

Error using RunTestCasesEP100 (line 56)

Invalid ModelName,

'C:/ggit/test/Project/MODEL/PhC200.slx',

specified in the SimulationInput object.

ModelName must be a valid Simulink model

name.

why?? what is wrong?/

What is the result of this command

which PhC200.slx

Also, should the forward slashes (/) as the file name separators be backslashes (\) ?

[TeraWatt]

found the isue. Need to enter ONLY the model name without file extention .slx,like this:

in(i) = Simulink.SimulationInput('C:/ggit/test/Project/MODEL/PhC200');

Hi, I understand that you want to run the Phc200.slx model located inside MODEL folder from a script that is located in the script folder.

To resolve this issue, you can try the following steps:

1. Instead of using the full file path, you can try specifying just the model name without the file extension. For example, if the model name is "PhC200.slx" and it resides in the "MODEL" folder, and your current MATLAB PATH is Project/MODEL you can use :

in(i) = Simulink.SimulationInput('PhC200');

2. Make sure that the current working directory in MATLAB is set to the project folder that contains the "SCRIPT" and "MODEL" folders. You can use the cd command to change the current working directory if needed.

3. if you are current working directory in MATLAB is either Project or Project/SCRIPT , you can use :

in(i) = Simulink.SimulationInput('MODEL/PhC200');
