Hi @ARJUN,

The image you attached indicates that the simulation is terminating with an error, suggesting a potential singularity in the solution. This issue is quite common and can typically arise from one of the following reasons:

• Modeling Error: There might be an error in the model causing the equations to diverge.
• Large Step Size: The step size used in the simulation might be too large.
• Division by Zero: There could be an instance of division by zero in the calculations.

To effectively resolve this issue, consider referring to the following MATLAB discussions and resources:

• https://blogs.mathworks.com/simulink/2024/07/22/derivative-of-state-1-in-block-x-y-integrator-at-time-0-55-is-not-finite/

These resources provide insights and solutions to address the singularity issue in the simulation.
