Detecting solver errors in compiled Simscape Multibody model

I have produced a Simscape Multibody model that works appropriately in the Simulink workspace. If I make unreasonable demands of the model's behaviour, it produces an error and the run stops.

We are going to use this model in a compiled environment.

How can we detect when an ‘impossible situation’ error occurs within the compiled model?

If such an error occurs, what will the compiled model do? Eg. does it stop at the last successful state?

Regards,

Andrew

Hi Andrew - the "impossible situation" is from a combination of the compiled model, solver settings, and inputs fed to the model. It depends on your compiled environment how failures will be handled, and to develop methods for ensuring "graceful failure".

Normally, we rely on unit testing to make sure the model will not be exposed to impossible situations, as well as limiting inputs and rate of change of inputs to reduce the risk that such a situation will occur.
