I am working on a simulink model which previously ran without problems. I replaced one block and resolved the bugs that simulink indicated to me upon running the model (I could see the bugs nicely in the Diagnostic Viewer). When I run the model now, the Diagnostics is empty and all that appears is this error message:
An error occurred while stepping through the simulation and the simulation was terminated
Caused by:
  • Reference to non-existent field 'form'.
There is no line or anything else indicated and I did not call any field or variable 'form', so I can't locate the problem. In case this information is useful, using the command 'lasterror' in the command window returns the identifier: 'Stateflow:translate:SFcnErrorStatus'. I am grateful for any hint on how to solve this issue.

They were both blocks consisting of several sub levels. The one I replaced it with consists mainly of connected matlab functions, hence the already mentioned bugs which were shown in the Diagnostics and which I could resolve.

Hi, Two steps to this problem:
1. Is there any stateflow in your model? Please remove it and check simulation. Corrupt MATLAB may not be able to execute Stateflow blocks.
2. If it still throws that error, is there any s-function block in your model? Please remove it and check simulation.

You can:
1. Delete it
2. Connect Terminator to its inputs
3. Connect Ground to its outputs
4. Check simulation.
