Next, click on the right side of the rectangle and (Click) Apply in the "Details of Convection" table. Then, set the Film Coefficient (i.e. convection coefficient, h) to 5 W/(m^2 C) and set the Ambient temperature to 0 degrees Celsius, as shown below. As we saw in Pre-Analysis, these dimensional settings correspond to a Biot number of 5.

This concludes the setup of the boundary value problem. We can move on to obtaining a numerical solution.
