Hello all, plate air cooling is the topic

I made 6points on the surface of plate to plot the temperature along the time.

After starting calcuation temperature of vertex is dropped sharply and increase slowly.

I think it is not physcal for cooling. usually temperature will be decreased very slowly for air cooling.

initial temp for plate is 780℃ , ambient air temp is 20℃

there is plot snap below please advise something. thanks
