Dear all,
I simulated a transient conjugate heat transfer problem.
A stacking material( up is metal and down is nonmetal, ex: iron stacks on wood) in air(300k),
Boundary coditions: up and down have a heat source(700k).
The result(I ran 2 seconds) was that nonmetal material had higher temperature than metal.
I am confused.
In our common sence,
the metal material should rise temperature fast,
but the simulation result is opposite.
Please a little help will be appreciated.
Thanks.
