Unformatted text preview: For the first time step, use an Euler (1 st order) time step. B. Repeat using ∆ x = 0.01 and 0.5 m, with C fl = 0.99. C. Compare the solutions for the L-F method at t = 6 s and t = 6 - ∆ t s for C fl = 0.99. D. Repeat using 4 th order central spatial differences with ∆ x = 0.1 and 0.01 m, C fl = 0.5 and 0.99 (at least one of these should be unstable). E. Use 1 st order Euler time step instead of L-F with C fl =0.5, ∆ x = 0.1 m, to see if an instability is present. Plot the results (e.g. ., with Tecplot). See the example Code distributed by email....
