I am trying to solve a dynamic energy balance on simulink and I build a model for that but I am getting error that derivative of state is becoming finite after some time. Erro is attached below. How can I resolve this issue. anyone please

Usually this is because the feedback loop is unstable. When this happens to me, I forgot some plus or minus, such there is negative or posivite feedback, while I needed the opposite, which yielded the system unstable, and the derivative inf
