The patterns of traveling wave on shallow water modeled by Green-Naghdi equation [PDF]

open access: yesMATEC Web of Conferences, 2022
The Green-Naghdi equations are a shallow water waves model which play important roles in nonlinear wave fields. By using the trial equation method and the Complete discrimination system for the polynomial we obtained the classification of travelling wave

Stabilization of the trial method for the Bernoulli problem in case of prescribed Dirichlet data [PDF]

open access: yes, 2013
We apply the trial method for the solution of Bernoulli’s free boundary problem when the Dirichlet boundary condition is imposed for the solution of the underlying Laplace equation and the free boundary is updated according to the Neumann boundary ...

Applying the meshless Fragile Points method to solve the two-dimensional linear Schrödinger equation on arbitrary domains [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2023
The meshless Fragile Points method (FPM) is applied to find the numerical solutions of the Schrödinger equation on arbitrary domains. This method is based on Galerkin’s weak-form formulation, and the generalized finite difference method has been used to ...

Trial methods for Bernoulli's free boundary problem [PDF]

open access: yes, 2014
Free boundary problems deal with solving partial differential equations in a domain, a part of whose boundary is unknown – the so-called free boundary. Beside the standard boundary conditions that are needed in order to solve the partial differential ...

Dynamics and optical solitons in polarization-preserving fibers for the cubic–quartic complex Ginzburg–Landau equation with quadratic–cubic law nonlinearity

open access: yesResults in Physics, 2023
In this paper, the cubic–quartic complex Ginzburg–Landau (CGL) equation is investigated by using the trial function method. The traveling wave hypothesis is applied to convert the CGL equation to an ordinary differential equation (ODE), which is ...
