The resulting MG renormalization (MGR) method is a natural generalization of the MG method for solving partial differential equations.
However in the case of MG method, the computational time to solve the Poisson's equation is at least 2 times faster in our simulation conditions.
We combine the multigrid (MG) method with state-of-the-art concepts from the variational formulation of the numerical renormalization group.
MG method is then applied in the case of the simulation of positive streamer propagation and its efficiency is evaluated from comparisons to SOR and MUMPS methods in the chosen point-to-plane configuration.
When the solution on a grid of N points is sought, our MGR method has a computational cost scaling as O log(N)), as opposed to O(N) for the best standard MG method.
The combined iterative solution scheme (MG-CCCS) is shown to feature significantly improved convergence rates over the classical MG method at energies where bound states dominate the solution, resulting in a fast and scalable solution method for the complex-valued Schrödinger break-up problem for any energy regime.
