Multigrid Method for Solution of 3D Helmholtz Equation Based on HOC Schemes
A higher order compact difference (HOC) scheme with uniform mesh sizes in different coordinate directions is employed to discretize a two- and three-dimensional Helmholtz equation.

An improved multigrid method for Euler equations
A new full approximation storage multigrid method has been developed for Euler equations. Instead of the usual approach of using frozen τ (the relative truncation error between fine and coarse grid levels), the relative truncation error is distributed ...

Multigrid Method for Solving Poisson-Boltzmann Equation
We present a first order accurate method for solving the partial differential equation, Poisson-Boltzmann Equation where the coefficients is assumed to be discontinuous across an interface and the source term is allowed to be a delta function.

Half-sweep algebraic multigrid (HSAMG) method applied to diffusion equations [PDF]
In previous studies, the efficiency of the Half-Sweep Multigrid (HSMG) method has been shown to be very fast as compared with the standard multigrid method. This is due to its ability to reduce computational complexity of the standard method.

Multigrid Methods for Computed Tomography
We consider the problem of computed tomography (CT). This ill-posed inverse problem arises when one wishes to investigate the internal structure of an object with a non-invasive and non-destructive technique. This problem is severely ill-conditioned, meaning it has infinite solutions and is extremely sensitive to perturbations in the collected data ...
