is used: (temperature : moisture concentration), (thermal conductivity : diffusion coefficient). The slab is assumed
to have a large surface area compared with its thickness and a negligible surface resistance. The density and
specific heat properties are arbitrarily set to 1.0 and the thermal conductivity is used for the diffusion coefficient
input. The solution is obtained for an arbitrary cross-sectional area of 1 ft2. ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–363 VM164
The initial integration time step of 0.434 hr. is determined from δ2/4D, where δ is a characteristic element length
(0.008333 ft) and D is the diffusion coefficient. Automatic time stepping is used to reduce the number of iterations
if possible. Results Comparison
