Correct solution needed here.This is Computational Fluid Dynamics Question.

Consider heat conduction in a slab of thickness L at steady state. The temperature at x=0 and x=L are T0 and TL, respectively. Calculate the temperature inside the slab for =17102cm2/s,L=0.06m,TL=100C, and T0=20C at different time intervals (i.e. 20 s and 360 s). Take 3 grid points into consideration
