A full discrete two-grid finite-volume method for a nonlinear parabolic problem. (English) Zbl 1221.65235
A nonlinear convection-diffusion problem in 2 is solved numerically with a fully discrete two-grid finite volume method. The method is based on solving the problem on a coarse mesh space and then take the resulting solution as the starting point to solve a linearized parabolic equation on the fine grid. The treatment largely parallels the one carried out by the first author [Appl. Math. Comput. 217, No. 19, 7546–7556 (2011; Zbl 1221.65234)] with a semi-discrete finite volume method. The numerical example chosen to illustrate the analysis is also the same.
