Multigrid Application On A New Coupled Elliptic Solver: A Preliminary Study.
Lim, Lay Ngor and Hj. Moh.d. Ali, Norhashidah (2003) Multigrid Application On A New Coupled Elliptic Solver: A Preliminary Study. Working Paper. Universiti Sains Malaysia.
A new multigrid scheme using halfsweep four-point explicit .decoupled group (EDG) method in solving the steady-state incompressible Navier-Stokes equation is presented. The concept of hallsweep multigrid was initiated by Othman and Abdullah (J 997) where promising results was established and confirmed. In this paper. we apply the multigrid V.cycle algorithm on the four point explicit decoupled group (EDG). In AIi and Abdullah . a new group iterative scheme. the Explicit Decoupled Group scheme, was developed as a more efficient Navier-Stokes solver on rotated grids compared to the iterative schemes based on the standard five-point formulae and the Alternating Group Explicit scheme due to Sahimi and Evans .
