摘要：
We consider a nonlinear elliptic boundary value problem, which describes a radiative heat transfer. This paper is concerned with the solution of the nonlinear system of equations arising from FEM approximations of the problem. We employ Newton's method to develop a new version of the two-grid method originated from O. Axelson and J. Xu. Numerical results are given to a simple problem with exact solution and to a simplified version of the physical problem.
