I am trying to run a transient analysis in SW13. the model consists of a copper tube fixed below a Aluminium plate, copper tube is maintained at 28F and plate is exposed to ambient air and I want to calculate the total time required for the plate to reach 30F, entire setup is placed at room temperature of 75F.

while running the analysis it shows the time left for the aalysis as 150 hours. Can some one please guide me where I am going wrong and what is the best procedure to run the analysis correctly
