Use the problem in Example 6.2 with ϕ = 1 to illustrate mesh refinement from n = 3 to n = 7.

Example 6.2

Show how the error in the finite difference approximation depends on the number of nodes n for the reaction–diffusion equation.

with c(0) = 0 and c(1) = 1. In chemical engineering lingo, the quantity ϕ is the Thiele modulus for this problem.
