I am trying to run a fairly complex hybrid vehicle model in Simulink, using Matlab2012b. The model has always worked fine until now. Today I created a Matlab script to call the model, run its initialization file, run the model, and gather some data for post-processing. This script ran successfully, once. On the second execution, Simulink failed to run, with the following error messages: Coder Error - unknown - Stateflow - Failed to create file: "model path".h Model error - unknown - Simulink - error using sf, error using construct_error(line 108), failed to create file: "...path and name...".h
What's more, when I try to run the model just in Simulink, it gives the same error. Normal, Accelerator, Rapid Accelerator give the same error. I tried the usual troubleshooting steps (restarts, mex -setup, clearing out slprj and mex32 files), and I re-installed the c++ compiler. Same error. I have tried running Matlab as administrator, and different versions of Matlab. Same error. It's like this model is set to no longer compile correctly.
I can run Matlab scripts and other Simulink models just fine. I have searched the forums and tried the other suggested solutions, but it hasn't fixed the problem. Any ideas out there??
