Multigrid Method for Solving the Poisson Equation in Cylindrical Coordinates on Graphics Processing Unit

Introduction. Solving elliptic partial differential equations, such as the Poisson equation, is a computationally expensive step in modeling physical processes in cylindrical engineering systems, including plasma traps and particle accelerators. The aim of the work is to create a high-performance implementation of a geometric multigrid method for cylindrical coordinates based on the technology of…
