Preconditioning the solution of the time-dependent neutron diffusion equation by recycling Krylov subspaces
After the spatial discretization of the neutron diffusion equation, a semidiscrete system of ordinary differential equations is obtained. This is a stiff system of differential equations, where the matrices involved are large and sparse. Usually, this system is solved using an implicit time discretization, which implies to solve an algebraic system of linear equations for this time step. This t...
متن کاملRecycling Krylov subspaces for CFD applications
The most popular iterative linear solvers in Computational Fluid Dynamics (CFD) calculations are restarted GMRES and BiCGStab. At the beginning of most incompressible flow calculations, the computation time and the number of iterations to converge for the pressure Poisson equation are quite high, since the initial guess is far from the solution. In this case, the BiCGStab algorithm, with relati...
متن کاملGalerkin Method for the Numerical Solution of the Advection-Diffusion Equation by Using Exponential B-splines
In this paper, the exponential B-spline functions are used for the numerical solution of the advection-diffusion equation. Two numerical examples related to pure advection in a finitely long channel and the distribution of an initial Gaussian pulse are employed to illustrate the accuracy and the efficiency of the method. Obtained results are compared with some early studies.
متن کاملNumerical solution of time-dependent foam drainage equation (FDE)
Reduced Differental Transform Method (RDTM), which is one of the useful and effective numerical method, is applied to solve nonlinear time-dependent Foam Drainage Equation (FDE) with different initial conditions. We compare our method with the famous Adomian Decomposition and Laplace Decomposition Methods. The obtained results demonstrated that RDTM is a powerful tool for solving nonlinear part...
متن کاملA numerical solution of a Cauchy problem for an elliptic equation by Krylov subspaces
We study the numerical solution of a Cauchy problem for a self-adjoint elliptic partial differential equation uzz − Lu = 0 in three space dimensions (x, y, z) , where the domain is cylindrical in z. Cauchy data are given on the lower boundary and the boundary values on the upper boundary are sought. The problem is severely ill-posed. The formal solution is written as a hyperbolic cosine functio...
