In Online MATLAB Simscape models will not run and give error

Hi,

In Online MATLAB (https://matlab.mathworks.com/) I am trying to run a Simscape example model, and I get an error when running:

Method 'update' is not defined for class 'SSC.SimscapeCC' or is removed from MATLAB's search path.

But when looking at Add-Ons, it shows Simscape installed.

Best regards

If it is a Simscape Example Model, you should ask MATLAB Product Support for help:

Hi Torsten,

Thank you for the reply, but no, it is not about the existing Simscape model.

I am using this just as an example of how I am not able to run any Simscape models; I cannot even see the Simscape library. Yet, the system says the Simscape is installed.

Are you sure you have a valid licence for Simscape ? You can check this by using

license('test','Simscape')

ans = 1

If the answer is "yes" and the problem continues, you should contact MATLAB Technical Support:

The answer is actually "no", but when I look at the add-ons, it says Simscape is installed.

You need a valid licence to use "Simscape" - it's not enough that it is installed.

The licence associated with your Email-address does not seem to cover "Simscape". Otherwise you should be able to use "Simscape" under MATLAB Online.

Without a licence or a free trial, it's only possible to use Simscape Onramp:

Hi Igor,

Sometimes testing of specific features can be turned off. You can try enabling them with a toggle using the license function. For example, for Simscape you can do:

license('test','simscape','enable') 

license('test','simscape')

if the second command returns 1, the feature is enabled. For more details, have look at the documentation here:

https://www.mathworks.com/help/matlab/ref/license.html

If it still returns 0, then it might be that the toolbox is not installed in your MATLAB Online session. In that case, you can try installing it from the Add-On Explorer:

• Go to the Home tab > Add-Ons > Get Add-Ons
• Search for the toolbox you need
• Click on it and install

I hope this helps, thanks!
