Part 2:

It is suggested that the number of elements should be increased to 100 to improve the accuracy of the

simulation. Without adjusting other parameters, use N = 100 and run your simulation.

a. Plot the concentration across the medium at the start (t = 0) and end (t = 10) of the simulation.

b. Explain your result. What else needs to change in order to run your simulation with more

elements? (Hint: see Example 2 in section 18.6 of your textbook)

c. Adjust the simulation parameters for stability with N = 100 elements. Run the simulation and plot

the concentration across the medium at the start (t = 0) and end (t = 10) of the simulation.
