A 1 ft2 area is used for the convection and conduction elements. Node 12 is given an arbitrary location. Automatic time stepping is used. The initial integration time step (ITS) chosen (14.5/80 = 0.18125 hr) is larger than the minimum ITS recommended; ITS ≈ δ2/4 α, where δ is the conduction element length (0.1 ft) and a is the thermal diffusivity (k/ρc = 0.01875 ft2/hr). POST26 is used to obtain the total heat transferred to the wall. ANSYS Verification Manual .
