Hey Rezvan,

I ran your code in R2024a, and I did not see any error. If you are facing this issue in a specific release, then you can try upgrading to a newer version of MATLAB.

To address the error in a specific release, please visit the following page to learn how to submit a technical support request with MathWorks:

I checked on R2020b (since the user was most likely using R2020a at the time of the post.) I confirm that the error message shows up.

I also get the error in R2024b.

Unfortunately I do not know how to debug the problem.

R2024b also reports

Warning: Simulation results could be inaccurate because the specified Reactance and Time constant values are resulting in an inconsistency in the calculation of the fundamental (internal) parameters of the model. Replace the 'NE39bus2_PQ/G10/G10' block in your model with a Synchronous Machine pu Fundamental block and provide the Stator, Field, and Dampers parameters.
