Hi Khelifa,

The error you are facing is because of the filename with which you are trying to save the model. Check the “Choose Valid Model File Names” section in the following MATLAB documentation to understand which file names are allowed - https://www.mathworks.com/help/simulink/ug/save-models.html#btiine0

Also, if you want to use the model in an older version of MATLAB, you may check the “Export Model to Previous Version Of Simulink” section in the above mentioned documentation page.
