Hello!
I'm trying to access the Simscape Onramp course in browser mode and the Simulink window refuses to open even after waiting for a long time.
The one time it did open, it showed an error when clicking on Submit for the very first assignment.
"Unrecognized function or variable 'simmechanics.sli.internal.register_datatypes'. (Figure atached)
Thanks!

Hi Joydeep,
  1. Coming to the problem of accessing the Simscape Onramp, Please ensure that your version of MATLAB is R2021a or later before proceeding. This can be confirmed by typing in >> ver at the MATLAB command line.
  2. You can choose to download the latest version if you have a licence or request for a free trial here : https://www.mathworks.com/campaigns/products/trials.html .
  3. When on a trial licence please acccess onramp courses from your MATLAB desktop application. Here are the steps to access Simscape Onramp from the MATLAB Command Window:
  • Open MATLAB, and ensure that you are logged into your account. Check the upper right corner to verify that you are signed in.
  • Type the command below in the Command Window:
learning.simulink.launchOnramp('simscape')
Now coming to the error message Undefined function or variable 'simmechanics.sli.internal.register_datatypes'. The root cause of this issue is under investigation. The workaround is to execute the following command from MATLAB Online.
>> addpath(fullfile(matlabroot,'toolbox/physmod/sm/sli/m'))

Hi Kannan,
Thanks for your reply.
I'm currently using the Matlab version: R2020b with limited possibility to update to a higher version as I'm working on a shared company asset.
This was the reason to access the course on the browser mode rather than the desktop mode, however was encountering some strange behavior and errors.
But thanks for providing the workaround. I'll give it a go!

Hello Joydeep,
I am experiencing the same error using the online training. Is there a fix?
In 2022b desktop training the whole RC Circuit lesson is blank, so I went to the online version as a workaround.

Hello，I can't use simscape Onramp with 2022b too, it open with a blank page, and when I come to online course, there is a error with "Unrecognized function or variable 'simmechanics.sli.internal.register_datatypes', any way to solve this?

It works！😀

Came here looking for the same issue with the browser version of Simscape Onramp.
Happy to confirm the workaround command worked, and I'm able to continue on!
