Hi I am facing some issues in converting from (.slx) version of models into (.mdl) version.

I opened the model in 2012b and made saveas to .mdl format but when i do this and open the model in 2011a all stateflow charts are converted to S-Functions. I am not able to work on this model in 2011a. what would be the problem?, can anyone suggest me how to convert .slx to .mdl?

Also, what is the error when you run the model in R2011a?
i have a similar problem. I use Matlab R2011b. Sometimes when i save my model, some stateflow charts will replaced by the S-function Block! I have no Idea why? The Simulation isnt possible because the mex File is missing. The main Problem is, i have no chance to get my Stateflow chart back. Does anyone have same problems or an solution? brg
If you are saving '.mdl' from menu [File]-[Save as] in Simulink menu, try saving model by [File]-[Export Model to...]-[Previous Version], and select version in the popped window.

I have faced this problem many times while working with multiple versions of MATLAB. I am not sure what is the exact reason but i feel designing a model with a higher version of MATLAB and opening the same in lower version corrupts Stateflow due to non - availability of the properties. Best option is to always Export model to previous version of MATLAB as per your need before opening the model in lower version. File ->Export Model to Previous Version -> Select the MATLAB version and Done
