I have been trying to follow this example from the Predictive Maintenance Toolbox tutorials.

When trying to build the model, I am faced with an error:

=== Build (Elapsed: 14 sec) ===
    ### Starting build procedure for model: pdmTransmissionCasing
    ### Generating code and artifacts to 'Model specific' folder structure
    ### Generating code into build folder: C:\Users\*****\Documents\MATLAB\Examples\predmaint\UsingSimulinkToGenerateFaultDataExample\pdmTransmissionCasing_rsim_rtw
    ### Build procedure for model: 'pdmTransmissionCasing' aborted due to an error.
    Error:Algebraic loops are not supported in generated code. Use the 'ashow' command in the Simulink Debugger to see the algebraic loops

I have tried changing some of the solver parameters such as making it variable-step to fix some previous errors (and changing the simulation file type), but the error still persists and I am unable to troubleshoot it within the model. I would really appreciate it if someone has suggestions for how to resolve this.

After some tinkering around with the model, I discovered that changing the solver configuration to "auto" helps solve this issue. I have since managed to run the simulations.
