Abstract:
Applying One-step Semi-Lagrangian forward method to the nonlinear Kortewegde Vries (KdV) equation, we investigated the numerical solutions of the KdV equation with three sets of initial data. The main difficulty was the interpolations from the irregularly distributed Lagrangian grid to the regularly distributed Eulerian grid. Two treatments were studied as local four points cubic interpolation and the cubic spline interpolation. The numerical solutions generated by the Zabusky and Kruskal scheme and Semi-Lagrangian forward method were compared.
