Two-grid method

WebApr 1, 2016 · The two-grid method involves solving one small, nonlinear coarse mesh system and two linear problems on the fine mesh which have the same stiffness matrix with only different right-hand side. WebJun 1, 2024 · Two-grid method was firstly introduced for nonselfadjoint or indefinite problems by Xu [32] and was developed for semilinear elliptic equations and nonlinear PDEs [33], [34] later. The basic idea of the two-grid algorithm is to solve a small nonlinear system on a coarse space, then solve simple linear system on the fine grid.
