This paper presents three regularized models for the logarithmic Klein-Gordon equation.By using a modified Crank-Nicolson method in time and the Galerkin finite element method(FEM)in space,a fully implicit energy-cons...
The higher-order numerical scheme of nonlinear advection-diffusion equations is studied in this article, where the space fractional derivatives are evaluated by using weighted and shifted Grünwald difference operator...
Large calculation error can be formed by directly employing the conventional Yee’s grid to curve surfaces.In order to alleviate such condition,unconditionally stable CrankNicolson Douglas-Gunn(CNDG)algorithm with is ...
