Hi!
A possible reason for getting this error is the incorrect implementation of the logic or the use of an unstable equation while creating the Simulink model. This happens if one of the blocks is generating either an Infinite or NaN value at some point in time, which gets passed to the block (mentioned in the error message) and thereby it generates the error message.
In order to find out which block was responsible for generating Infinite or NaN value you can set the configuration parameters by performing the steps below:
- Go to 'Model Settings' of Top Model from Toolstrip
- Search for 'Inf or NaN block output' using the search bar present above in the Configuration Parameters panel.
- Set the value of 'Inf or NaN block output' to 'error' (by default it would be 'none')
- Click Apply and OK. Run the model again.
Now you can see an error in the 'Diagnostic Viewer' which points out the block that is creating Infinite or NaN value.
To avoid such errors, you can always check for any logical errors relating to that block (For ex. Division by zero) or equations that can be corrected.
