Error with running a Simulink model.

I have a run file to run the fowards facing model of this electric motor and this is whats happens...

Every time I run the forwards model matlab run file and then go on my backwards model and run it I get these 4 errors. But if I don’t run the run file and then run the backwards model straight away, it works every time with no errors and the correct outputs.Any ideas?

Without the files is not easy to tell where the problem is. I suspect when you run the first model some parameters from the workspace are either overwritten or deleted from workspace which will result in the errors when running the second model. First, I would check all callbacks and the names used for data logging. I hope this helps.

Thank you, I'm going to go back through all the loaded in files in the run file and see if they all work correctly.

So i created a new model and put a sine wave block in the used a to workspace block to see if it was my simulink model. It still didn't put that variable in my workspace. Is there a setting that i may have changed to stop variables going into my workspace?

May be that 'Single simulation output' is enabled in the Configuration Parameters. If that's the case the data is saved as 'out' (or a different name if changed) in the workspace.
