Problem 3

Recreate the response history from HW #2, Problem 3 using the CDM tool you created as part of

Problem 2. Select a time step, At that will produce an error that is smaller than 2% compared to

the analytical solution. Check the three requirements per Module 3, Slide 10!

Note: As part of the accuracy requirement, you may plot the analytical solution in the same figure

as your numerical solution. Additionally, you may also plot the difference between the two, which

can be interpreted as the error.
