Renaming simulink mdl files

When renaming simulink model files (mdl/slx), whether using 'save as' or renaming the file within windows explorer I recieve the following error:

"Error loading the initial state for model 'model'. Unable to find a matching block state corresponding to element 1 of signals structure array"

Reinstating the original file name, the model executes without issue. Any reason why the number states of the system might be seen to vary dependant on the model name?

The error appears to refer to an issue with the initial states of the model defined in the configuration parameters GUI (though I dont believe this to be the source of the problem). I have defined the initial states using the getstruct statment 'getstatestruct(operating_point)'.

To retain version control I have had to resort to copying each iteration of the design and dependant files to new folders. This is proving a real pain!

A 'fix' would be greatly appreciated!!

Many Thanks

That might be related to a bug, see bug report

It may also be related to configuration parameter settings:

- Open the Configuration Parameters -> Data Import/Export pane - Check the boxes with 'Time' and 'States', select the 'Format' option to 'Array'

It general, you issue might be release or model specific and thus contacting Technical Support may be the best for you.

The link behind my note a above was

Which for some reason is not working anymore. I changed it to

I personally also have issues with IE, but it workes in Chrome.

Hi Andreas,

Thank you kindly for the response. The issue would indeed appear to be linked to the bug report you provided (the model contains both memory blocks and S functions with states).

Much appreciated.
