2D TRANSIENT Heat Transfer Problem

Hi everyone,

I am encountering an error in the time dependent situation - Failed to find consistent initial values, last time steps not converged.

I have specified 'initial values' and the required boundary conditions, also I used the finest mesh available in the model already. The error still comes out.

Please find attached my model for details.

I have previously done a Stationary scenario for the same model, there was no problem, and gave a very logical solution. Once I changed it to Time Dependent, I have this problem.

It would be greatly appreciated if someone can advise or assist.

Thank you in advance.

Kind regards,

Gary Yu
