Visualization Study of fKdV Equation Simulation with Matlab
Numerical simulation results of fKdV equation are illustrated in the forms of waterfall with Matlab. Matlab can solve many complicated engineering problem and the numerical results can be showed by its excellent graphics. The forced Kortewege-de Vries (fKdV) equation was regarded as a classical nonlinear model when the resonant flow was happened. Which involves a balance between non-linearity and dispersion at leading-order and the effect of the bottom. The pseudo-spectral method based on function approach was good for solving nonlinear equation, and it is convenience to program with the Matlab for PS method. With the results, we can get some conclusion about the effect of the different bottom on surface wave.
