Computational Methods for PDE's II

Homeworks

• HOMEWORK #4:
  This is the second of two problem sets using spectral methods. In THIS problem set we solved Burgers equation using the pseudospectral and the collocation methods. This is a classic PDE problem where we compared our numerical results to our analytical solution.

Matlab Code

@ t = p/8

@ t = 2*p/8

• HOMEWORK #3:
  This is the first of two problem sets using spectral methods. In THIS problem set we were asked to test out the Finite Difference, Finite Element, and two spectral methods and compare their results against the analytical solution to a first derivative problem seen here.
