OSTI ID:6166858
The multigrid method, which employs a sequence of nested grids in the solution process, is a general numerical technique for solving continuous problems. Implementation of the multi-grid algorithm can result in higher accuracy and efficiency than methods with fixed grid size and fixed order of approximation, and specific tests of this are considered. An introduction to the implementation of the multigrid method in the solution of time-dependent partial differential equations is presented. Multigrid solutions for the advection equation are compared with published results using the usual fixed-grid method. 2 figures.
