A finite pointset method for Kuramoto–Sivashinsky equation based on mixed formulation L. Jones Tarcius Doss, N. Kousalya Mathematical Methods in the Applied Sciences, 2025 In this paper, a second‐order splitting method is applied to the Kuramoto–Sivashinsky equation, and then a finite Pointset method (FPM) is employed to solve the resulting coupled system. FPM is a meshfree particle method which is a local iterative procedure based on the weighted least square approximation. The numerical example confirms that the FPM is effective and accurate for this kind of problem.
A Finite Pointset Method for Extended Fisher-Kolmogorov Equation Based on Mixed Formulation L. Jones Tarcius Doss, N. Kousalya International Journal of Computational Methods, 2021 In this paper, numerical solutions of the extended Fisher–Kolmogorov equation are obtained using finite pointset method. Finite pointset method is a meshless method which is a local iterative method based on the weighted least square approximation. By employing splitting technique, the extended Fisher–Kolmogorov equation is split into a two coupled system of differential equations by introducing an intermediate function. The method is applied to the resulting coupled system of differential equation. The numerical results confirm the good efficiency of the finite pointset method.
