Answer 1 of 2. Both the spatial domain and time interval if applicable are discretized or broken into a finite number of steps and the value of the solution at these discrete points is approximated by solving algebraic. It represents heat transfer in a slab which is insulated at.

Like all numerical methods each have their pros and cons. This approximation is the forward time central spacemethod from equation 111 with the diffusion terms removed. With an insulator heat fluxdtdx at 0tzeroat left boundary condition and temperature at the right boundary t lt is zero and initial temperature 20 degree centigrade and length of the rod is 02m and thermal diffusivity alpha0001. If the internal temperature of a body remains relatively constant with respect to distance can be treated as a.
