1 Oct. 24, 2006 ATMS 502 - CS 505 - CSE 566 Jewett Hints: Computer Problem 4 To make things simple, read in the type of problem (rotational/deformational case), the cone radius and origin, and the time step and plot interval. As with computer problem 3, it is often easiest to debug by first running the problem for 10 steps, plotting each step, while looking for problems. Your initiation step now requires initializing the two wind components u(x,y) and v(x,y) as well as the scalar field q(x,y). Remember their physical dimensions will not be the same; u() has an extra point in the X direction, and v() in Y. You will be handling a single row or column at a time when doing advection, so you will be copying a row or column of q and of u (or v) to 1D arrays. You can implement boundary conditions there – in 1D – so q() can be q(nx,ny), and your 1D array can have the extra points needed as boundary points for advection.
