چکیده
A new method is developed to approximate a first-order Hamilton–Jacobi equation. The constant motion of an interface in the normal direction interest. captured with help “Level-Set” function approximated through finite-volume Godunov-type scheme. Contrarily most computational approaches that consider smooth Level-Set functions, present one considers sharp “Level-Set”, numerical diffusion being controlled Overbee limiter (Chiapolino et al. J Comput Phys 340:389–417, 2017). requires gradient computation addressed least squares approximation. Multidimensional results on fixed unstructured meshes are provided and checked against analytical solutions. Geometrical properties such as interfacial area volume well. Results show excellent agreement exact

A uniform approximation method to solve absolute value equation
In this paper, we propose a parametric uniform approximation method to solve NP-hard absolute value equations. For this, we uniformly approximate absolute value in such a way that the nonsmooth absolute value equation can be formulated as a smooth nonlinear equation. By solving the parametric smooth nonlinear equation using Newton method, for a decreasing sequence of parameters, we can get the ...
متن کاملOn convergence of homotopy analysis method to solve the Schrodinger equation with a power law nonlinearity
In this paper, the homotopy analysis method (HAM) is considered to obtain the solution of the Schrodinger equation with a power law nonlinearity. For this purpose, a theorem is proved to show the convergence of the series solution obtained from the proposed method. Also, an example is solved to illustrate the eciency of the mentioned algorithm and the h-curve is plotted to determine the region ...
متن کاملRunge-Kutta discontinuous Galerkin method using a new type of WENO limiters on unstructured meshes
In this paper we generalize a new type of limiters based on the weighted essentially nonoscillatory (WENO) finite volume methodology for the Runge-Kutta discontinuous Galerkin (RKDG) methods solving nonlinear hyperbolic conservation laws, which were recently developed in [31] for structured meshes, to two-dimensional unstructured triangular meshes. The key idea of such limiters is to use the en...
