- Block 'BlockName' outputs 'NaN' for element x of output port x at major time step 0
An error occurred while running the simulation and the simulation was terminated due to singularities in my Simulink model?

- Derivative of state '1' in block 'pmsm_ini_dc_bus/PID Controller/Integrator/Continuous/Integrator' at time 11.00046 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)

This problem occurs oftenly. This is usually caused because of Inf or NaN output produced at a block. Set the diagnostic "Inf or NaN block output" to error in the configuration settings. If this is the issue, you will get the error as follows:
An error occurred while running the simulation and the simulation was terminated
where BlockName is the block in which error is thrown.
You can debug your model from there to bypass NaN or Inf values from reaching the integrator.
